An antistreptolysin is an antibody made against streptolysin.
ASO stands for antistreptolysin-O, which is an antibody your body makes against streptococcus bacteria.
I looked up this word in the MedlinePlus website. They can tell you what it means. Evidently, according to them, it's not a disease or condition; it's a test.
to determine whether a previous group A Streptococcus infection has caused a poststreptococcal disease, such as scarlet fever, rheumatic fever, or a kidney disease called glomerulonephritis.
This test shows a past infection of Group A Streptococcal bacteria, which can cause a sore throat and is seen fairly commonly in children. It will go away by itself and doesn't normally need medication. There is a possible, rare complication that may occur that affects the kidneys called post-streptococcal glomerulonephritis. Watch out for any swelling, lower back pain, difficulty urinating or feeling tired.
Serology (ser -> serum; ology -> study of) is the set of experiments and tests that can be done using serum. Serum is the non-cellular component of blood. That is, it's the liquid (with all its lipids and proteins) that is left over after all the red and white blood cells have been removed. Serology could involve the measurement of antibody titers (amounts) or cytokine concentrations.
Scarlet fever is a disease caused by an exotoxin released by Streptococcus pyogenes. It is characterized by sore throat, fever, a 'strawberry tongue', and a fine sandpaper rash over the upper body that may spread to cover the uvula (Forchheimer spots). * Bright red tongue with a "strawberry" appearance * Characteristic rash, which: * is fine, red, and rough-textured; it blanches upon pressure * appears 12-48 hours after the fever * generally starts on the chest, axilla (armpits), and behind the ears * is worse in the skin folds * Pastia lines (where the rash becomes confluent in the arm pits and groins) appear and persist after the rash is gone * The rash begins to fade three to four days after onset and desquamation (peeling) begins. "This phase begins with flakes peeling from the face. Peeling from the palms and around the fingers occurs about a week later ."[1] Peeling also occurs in axilla, groin, and tips of the fingers and toes.[2] Diagnosis of scarlet fever is clinical. The blood tests shows marked leukocytosis with neutrophilia and conservated or increased eosinophils, high erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), and elevation of antistreptolysin O titer. Blood culture is rarely positive, but the streptococci can usually be demonstrated in throat culture. The complications of scarlet fever include septic complications due to spread of streptococcus in blood and immune-mediated complications due to an aberrant immune response. Septic complications, today rare, include ear and sinus infection, streptococcal pneumonia, empyema thoracis, meningitis and full-blown sepsis, upon which the condition may be called malignant scarlet fever. Immune complications include acute glomerulonephritis, rheumatic fever and erythema nodosum. The secondary scarlatinous disease, or secondary malignant syndrome of scarlet fever, includes renewed fever, renewed angina, septic ear, nose, and throat complications and kidney infection or rheumatic fever and is seen around the eighteenth day of untreated scarlet fever.
it uses bacteria and mouse urine and then spreads to the legs and then body
DefinitionAntistreptolysin O (ASO) titer is a blood test to measure antibodies against streptolysin O, a substance produced by Group A Streptococcus bacteria.Alternative NamesASO titer; ASLOHow the test is performedBlood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.The blood is then sent to the laboratory for analysis.How to prepare for the testYou should not eat for 6 hours before the test.How the test will feelWhen the needle is inserted to draw blood, you may feel moderate pain, or only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedThis test is used to detect prior infection by Group A Streptococcus, the bacteria responsible for diseases such as:Bacterial endocarditisGlomerulonephritisRheumatic feverScarlet feverStrep throatThe ASO antibody may be found in the blood weeks or months after the strep infection has gone away.Normal ValuesNormal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanAbnormal results may be due to:Active streptococcal infectionBacterial endocarditisPost-streptococcal glomerulonephritisRheumatic feverScarlet feverWhat the risks areVeins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.Other risks associated with having blood drawn are slight but may include:Excessive bleedingFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)ReferencesBisno AL, Stevens DL.

Scarlet fever is one step higher then a strep throat it can even kill you some of the problems you may have are - chills -neck swollen of a fever that goes up to 101, Scarlet fever produces poisons toxins in your body and that is when it turns into Streptococcal toxic shock syndrome and that puts toxic gas into your system and that is how you die of scarlet fever Scarlet fever gives you all of the above, and also it can produce a generalized rash that involves even the palms and the soles. A serious complication of Scarlet fever is Post streptococcal glomerulonephritis, an acute kidney disease causing blood in the urine, increase blood pressure and generalized swelling, especially the face. This kidney problem appears 10 to 14 days after the skin infection. Scarlet Fever is a communicable disease that is highly contagious. It is much more serious than strep throat. Persons with Scarlet Fever may experience high fever, chills, severe ear aches, and rash. Death may occur. Often while recovering the skin may peal.
