Before birth, an infant gets rid of bilirubin through the mother's blood and liver systems. After birth, the baby's liver has to take over processing bilirubin on its own.

What is the significance of 1.5mg bilirubin lab results?
Depends on if you're talking about a newborn or an adult. Newborns have a higher normal range than adults. For instance, in Colorado we establish a certain range from the normal population that may differ from the rest of the nation. Adults can run up to 1.0 mg/dl. Anything from 0 to 1.0 mg/dl is considered normal. 1.5 mg/dl is high and may require additional lab work or other studies to determine the cause of the high bilirubin. The physician may request that the lab break the bilirubin test down into direct vs. indirect bilirubin. Direct bilirubin is a measure of how much of the bilirubin is not soluble and therefore not excreted in the urine. Sunlight can actually "conjugate the bilirubin" to make it more soluble in the urine and therefore excretable in the urine. This is why they put babies with "jaundice" or high bilirubin under bili lights. Bili lights will help turn the unconjugated biliruben into soluble biliruben which can then be excreted in the urine. Increased bilirubin in adults can point to several disease states like cirrhosis of the live due to viral hepatitis, alcoholism or other factors. Very high bilirubin levels in infants can cause brain damage, so treatment like exchange transfusion may be in order.

Why would newborn babies be exposed to sunshine?
0-6 months: Infants under 6 months of age should be kept out of the sun. Their skin is too sensitive for sunscreen. An infant's skin possesses little melanin, the pigment that gives colour to skin, hair and eyes and provides some sun protection. Therefore, babies are especially susceptible to the sun's damaging effects.So it isn't really safe but, only some people do it but, there isn't a clear reason why.HERE IS ANOTHER ANSWER:A common condition for newborns is jaundice (yellowing of the skin and sclera of the eyes). Jaundice occurs when the baby produces more bilirubin than the liver can process. Bilirubin is a by product of normal breakdown of red blood cells. The three most common reasons for excess bilirubin are excess production of bilirubin due to the baby's normally higher than adult turn over of red blood cells, immature liver that cannot keep up with normal bilirubin production, or reabsorption of bilirubin by the intestines. the most common treatment of jaundice is phototherapy, the exposure of the child to special lighting that helps alter the by product to make it easier for the child's liver to process it. Some pediatricians may suggest the exposure of the child to brief periods of natural daylight if bilirubin levels are below 15-25mg.
Why is there jaundice in neonatal sepsis?
I'm assuming its because of liver damage. Meninigitis can cause ICP and SIADH as well as DIC (Diseeminated intravascular coagulation) in other words little clots all throughout the body. Increased water due to SIADH can cause damage on internal organs hence liver failure.
Newborn jaundice?
DefinitionNewborn jaundice is a condition marked by high levels of bilirubin in the blood. The increased bilirubin cause the infant's skin and whites of the eyes (sclera) to look yellow.Alternative NamesJaundice of the newborn; Neonatal hyperbilirubinemiaCauses, incidence, and risk factorsBilirubin is a yellow pigment that's created in the body during the normal recycling of old red blood cells. The liver processes bilirubin in the blood so that it can be removed from the body in the stool.Before birth, the placenta -- the organ that nourishes the developing baby -- removes the bilirubin from the infant so that it can be processed by the mother's liver. Immediately after birth, the baby's own liver begins to take over the job, but this can take time. Therefore, bilirubin levels in an infant are normally a little higher after birth.High levels of bilirubin in the body can cause the skin to look yellow. This is called jaundice. Jaundice is present to some degree in most newborns. Such "physiological jaundice" usually appears between day 2 and 3, peaks between days 2 and 4, and clears by 2 weeks. Physiological jaundice usually causes no problems.Breast milk jaundice is another common, usually non-harmful form of newborn jaundice. Breast milk may contain a substance that increases reuse of bilirubin in the intestines. Such jaundice appears in some healthy, breastfed babies after day 7 of life, and usually peaks during weeks 2 and 3. It may last at low levels for a month or more.Breastfeeding jaundice is a type of exaggerated physiological jaundice seen in breastfed babies in the first week, especially in those that are not nursing often enough. Breastfeeding jaundice is different than breast milk jaundice, which occurs later and is caused by the milk itself.Sometimes jaundice can be a sign of a serious underlying problem. Higher levels of bilirubin can be due to:An event or condition that increases the number of red blood cells that needs to be processedAnything that interferes with the body's ability to process and remove bilirubinThe following increase the number of red blood cells that need to be processed:Abnormal blood cell shapes Congenital spherocytic anemiaElliptocytosisBlood type incompatibilities ABO incompatibility (Mother has type O blood, baby does not)Rh incompatibility (Mother is Rh negative, baby is not)Cephalohematoma or other birth injuryGlucose-6-phosphate dehydrogenase deficiencyHigh levels of red blood cells (polycythemia) More common in small for gestational age babiesMore common in some twinsInfectionPrematurityPyruvate kinase deficiencyTransfusionsThe following interfere with the body's ability to process and remove bilirubin:Alpha-1 antitrypsin deficiencyBiliary atresiaCertain medicationsCongenital cytomegalovirus (CMV) infectionCongenital herpesCongenital hypothyroidismCongenital rubellaCongenital syphilisCongenital toxoplasmosisCrigler-Najjar syndromeCystic fibrosisGaucher's diseaseGilbert syndromeHypoxiaInfections (such as sepsis)Lucey-Driscol syndromeNeonatal hepatitisNiemann-Pick diseasePrematurityIn otherwise healthy babies born at 35 weeks gestation or greater, those most likely to eventually develop signs of newborn jaundice are those who have:A brother or sister who needed phototherapy for jaundiceA high bilirubin level for their age, even if they are not yet jaundicedBeen exclusively breastfeed, especially if weight is excessiveBlood group incompatibility or other known red blood cell diseaseCephalohematoma or significant bruisingEast Asian ancestryJaundice in the first 24 hours of lifeSymptomsThe main symptom is a yellow color of the skin. The yellow color is best seen right after gently pressing a finger onto the skin. The color sometimes begins on the face and then moves down to the chest, belly area, legs, and soles of the feet.Sometimes, infants with significant jaundice have extreme tiredness and poor feeding.Signs and testsAll newborns should be examined for jaundice at least every 8 to 12 hours for the first day of life.Any infant who appears jaundiced in the first 24 hours should have bilirubin levels measured immediately. This can be done with a skin or blood test.Babies should be assigned a risk for later developing jaundice before they leave the hospital. Babies are classified as low risk, low intermediate risk, high intermediate risk, or high risk. Many hospitals do this by routinely checking total bilirubin levels on all babies at about 24 hours of age.Further testing varies on the infant's specific situation and test results. For example, the possible cause of the jaundice should be sought for babies who require treatment or whose total bilirubin levels are rising more rapidly than expected.Tests that will likely be done include:Complete blood countCoomb's testMeasurement of levels of specific types of bilirubinReticulocyte countThe level of albumin in the baby's blood may also be checked. Low albumin levels may increase the risk of damage from excessive jaundice.TreatmentTreatment is usually not necessary. Keep the baby well-hydrated with breast milk or formula. Frequent feedings encourage frequent bowel movements, which helps remove bilirubin through the stools. (Bilirubin is what gives stool a brown color).Sometimes special blue lights are used on infants whose levels are very high. This is called phototherapy. These lights work by helping to break down bilirubin in the skin. The infant is placed naked under artificial light in a protected isolette to maintain constant temperature. The eyes are protected from the light. The American Academy of Pediatrics recommends that breastfeeding be continued through phototherapy, if possible.In the most severe cases of jaundice, an exchange transfusion is required. In this procedure, the baby's blood is replaced with fresh blood. Treating severely jaundiced babies with intravenous immunoglobulin may also be very effective at reducing bilirubin levels.Expectations (prognosis)Usually newborn jaundice is not harmful. For most babies, jaundice usually resolves without treatment within 1 to 2 weeks. However, if significant jaundice is untreated, very high levels of bilirubin can damage the brain. For babies who require treatment, the treatment is usually quite effective.ComplicationsRare, but serious, complications from high bilirubin levels include:Cerebral palsyDeafnessKernicterus -- brain damage from very high bilirubin levelsCalling your health care providerAll babies should be seen by a health care provider in the first 5 days of life to check for jaundice.Those who spend less than 24 hours in a hospital should be seen by age 72 hours.Infants sent home between 24 and 48 hours should be seen again by age 96 hours.Infants sent home between 48 and 72 hours should be seen again by age 120 hours.Jaundice is an emergency if the baby has a fever, has become listless, or is not feeding well. Jaundice may be dangerous in high-risk newborns.Jaundice is generally NOT dangerous in term, otherwise healthy newborns. Call the infant's health care provider if jaundice is severe (the skin is bright yellow), if jaundice continues to increase after the newborn visit, lasts longer than 2 weeks, or if other symptoms develop. Also call the doctor if the feet, particularly the soles, are yellow.PreventionIn newborns, some degree of jaundice is normal and probably not preventable. The risk of significant jaundice can often be reduced by feeding babies at least 8 to 12 times a day for the first several days and by carefully identifying infants at highest risk.All pregnant women should be tested for blood type and unusual antibodies. If the mother is Rh negative, follow-up testing on the infant's cord is recommended. This may also be done if the mother blood type is O+, but it not necessarily required if careful monitoring takes place.Careful monitoring of all babies during the first 5 days of life can prevent most complications of jaundice. Ideally, this includes:Considering a baby's risk for jaundiceChecking bilirubin level in the first day or soScheduling at least one follow-up visit the first week of life for babies sent home from the hospital in 72 hoursReferencesAmerican Academy of Pediatrics (AAP).

Bilirubin - blood?
DefinitionBilirubin is a yellowish pigment found in bile, a fluid produced by the liver.This article discusses the laboratory test done to measure bilirubin in the blood. Total and direct bilirubin are usually measured to screen for or to monitor liver or gallbladder problems. Large amounts of bilirubin in the body can lead to jaundice.A test may also be done to measure bilirubin in a urine sample. For information on that test, see: Bilirubin - urine.Alternative NamesTotal bilirubin - blood; Unconjugated bilirubin - blood; Indirect bilirubin - blood; Conjugated bilirubin - blood; Direct bilirubin - bloodHow the test is performedA blood sample is needed. For information on how this is done, see: Venipuncture.The laboratory specialist spins the blood in a machine called a centrifuge, which separates the liquid part of the blood (serum) from the cells. The bilirubin test is done on the serum.How to prepare for the testYou should not eat or drink for at least 4 hours before the test. Your health care provider may instruct you to stop taking drugs that affect the test.Drugs that can increase bilirubin measurements include allopurinol, anabolic steroids, some antibiotics, antimalaria medications, azathioprine, chlorpropamide, cholinergics, codeine, diuretics, epinephrine, meperidine, methotrexate, methyldopa, MAO inhibitors, morphine, nicotinic acid, birth control pills, phenothiazines, quinidine, rifampin, steroids, sulfonamides, and theophylline.Drugs that can decrease bilirubin measurements include barbiturates, caffeine, penicillin, and high-dose salicylates such as aspirin.Why the test is performedThis test is useful in determining if a patient has liver disease or a blocked bile duct.Bilirubin metabolism begins with the breakdown of red blood cells in many parts of the body. Red blood cells contain hemoglobin, which is broken down to heme and globin. Heme is converted to bilirubin, which is then carried by albumin in the blood to the liver.In the liver, most of the bilirubin is chemically attached to another molecule before it is released in the bile. This "conjugated" (attached) bilirubin is called direct bilirubin; unconjugated bilirubin is called indirect bilirubin. Total serum bilirubin equals direct bilirubin plus indirect bilirubin.Conjugated bilirubin is released into the bile by the liver and stored in the gallbladder, or transferred directly to the small intestines. Bilirubin is further broken down by bacteria in the intestines, and those breakdown products contribute to the color of the feces. A small percentage of these breakdown compounds are taken in again by the body, and eventually appear in the urine.Normal ValuesDirect bilirubin: 0 to 0.3 mg/dLTotal bilirubin: 0.3 to 1.9 mg/dLNote: mg/dL = milligrams per deciliterNormal values may vary slightly from laboratory to laboratory.What abnormal results meanJaundice is a yellowing of the skin and the white part of the eye, which occurs when bilirubin builds up in the blood at a level greater than approximately 2.5 mg/dL. Jaundice occurs because red blood cells are being broken down too fast for the liver to process. This might happen due to liver disease or bile duct blockage.If the bile ducts are blocked, direct bilirubin will build up, escape from the liver, and end up in the blood. If the levels are high enough, some of it will appear in the urine. Only direct bilirubin appears in the urine. Increased direct bilirubin usually means that the biliary (liver secretion) ducts are obstructed.Increased indirect or total bilirubin may be a sign of:Crigler-Najjar syndromeErythroblastosis fetalisGilbert's diseaseHealing of a large hematoma (bruise or bleeding under the skin)Hemolytic anemiaHemolytic disease of the newbornHepatitisPhysiological jaundice (normal in newborns)Sickle cell anemiaTransfusion reactionPernicious anemiaIncreased direct bilirubin may indicate:Bile duct obstructionCirrhosisDubin-Johnson syndrome (very rare)HepatitisIntrahepatic cholestasis (buildup of bile in the liver) due to any causeAdditional conditions under which the test may be performed:Biliary strictureCholangiocarcinomaCholangitisCholedocholithiasisHemolytic anemia due to G6PD deficiencyHepatic encephalopathyIdiopathic aplastic anemiaIdiopathic autoimmune hemolytic anemiaImmune hemolytic anemia (including drug-induced immune hemolytic anemia)Secondary aplastic anemiaThrombotic thrombocytopenic purpuraWilson's diseaseSpecial considerationsFactors that interfere with bilirubin testing are:Hemolysis (breakdown) of blood will falsely increase bilirubin levelsLipids in the blood will falsely decrease bilirubin levelsBilirubin is light-sensitive; it breaks down in lightReferencesBerk PD, Korenblat KM.
