How long back do hair drug tests go?
For as long as you have had the hair. If you haven't had a hair cut in three months and did drugs 2 1/2 months ago, the proof will be there.
Hair drug testing is one of the important techniques to find presence of drug. Another drug testing includes blood, saliva, urine test etc
Can ab neg and o pos have a baby o neg?
No. The baby could have a negative Rh factor, but it would have either the A or B blood group.
What does low AG ratio calc mean?
- How is it used?
Total protein measurements can reflect nutritional status and may be used to screen for and help diagnose kidney disease, liver disease, and many other conditions. Sometimes conditions are first detected with routine testing before symptoms have begun to appear. If total protein is abnormal, further tests must be performed to identify which specific protein is abnormally low or high so that a specific diagnosis can be made.

When is it ordered?A total protein test is one component of a Comprehensive Metabolic Panel (CMP) that is often ordered as part of a routine health checkup. Total protein may also be ordered to provide general information about your nutritional status, such as when you have undergone a recent weight loss. It can be ordered along with several other tests to provide information if you have symptoms that suggest a liver or kidney disorder or to investigate the cause of abnormal pooling of fluid in tissue (edema).

What does the test result mean?Results of a total protein test will give your doctor information on your general health status with regard to your nutrition and/or conditions involving major organs, such as the kidney and liver. However, if results are abnormal, further testing is usually required to help diagnose the disease affecting protein levels in the blood.
Low total protein levels can suggest a liver disorder, a kidney disorder, or a disorder in which protein is not digested or absorbed properly. Low levels may be seen in severe malnutrition and with conditions that cause malabsorption, such asCeliac disease or inflammatory bowel disease (IBD).
High total protein levels may be seen with chronic inflammation or infections such as viral hepatitis or HIV. They may be caused by bone marrow disorders such as multiple myeloma.
Some laboratories also report the calculated ratio of albumin to globulins, termed the A/G ratio. Normally, there is a little more albumin than globulins, giving a normal A/G ratio of slightly over 1. Because disease states affect the relative changes in albumin and globulins in different ways, this may provide a clue to your doctor as to the cause of the change in protein levels. A low A/G ratio may reflect overproduction of globulins, such as seen in multiple myeloma or autoimmune diseases, or underproduction of albumin, such as occurs with cirrhosis, or selective loss of albumin from the circulation, as occurs with kidney disease (nephrotic syndrome). A high A/G ratio suggests underproduction of immunoglobulins as may be seen in some genetic deficiencies and in some leukemias. More specific tests, such as albumin, liver enzyme tests, and serum protein electrophoresis must be performed to make an accurate diagnosis.

Is there anything else I should know?Prolonged application of a tourniquet during blood collection can result in a blood sample that has a higher protein concentration than the rest of the circulation. This will mean that the test result for total protein will be falsely elevated (higher than the actual concentration in the circulation).
Drugs that may decrease protein levels include estrogens and oral contraceptives.
What does low osmotic fragility means?
Osmotic fragility usually (unless otherwise mentioned) refers to the ease with which Red Blood Cells (RBCs) undergo lysis in a hypotonic solution.
Before knowing what 'low osmotic fragility' means, one should know the concept of osmotic fragility. Different parameters, some of them related to the RBC and some of the extracellular environment have an effect on osmotic fragility.
Low osmotic fragility means that the RBCs have a resistance against undergoing lysis when suspended in solutions which are hypotonic. They undergo lysis only if the solution is extremely hypotonic.
In contrast, high osmotic fragility refers to the tendency of the RBCs to lyse even if the solution in which they are suspended in is mildly hypotonic.
As an example for low osmotic fragility would be thalassemia.
And as an example for high osmotic fragility, spherocytosis (a hereditary condition where the RBCs lose their usual biconcave structure and become spherical) causes increased osmotic fragility. i.e, It very easily lyses even at solutions which are mildly hypotonic...
p.s
Another interesting point to note is that in sickle cell anemia, the RBCs show increased mechanical fragility but decreased osmotic fragility. Elucidated by the fact that post-splenectomy the RBC lifespan increases.
What will the court do if you fail an etg test?
Depends on why you're being tested, and on the court's opinion of the situation. It may also depend on the laws in your state. That's why the court are called "judges."
Decreased complement activity is a hallmark of which diseases?
Decreased complement activity may be seen in:
- Cirrhosis
- Glomerulonephritis
- Hereditary angioedema
- Hepatitis
- Kidney transplant rejection
- Lupus nephritis
- Malnutrition
- Systemic lupus erythematosus
Explain the properties of cohesion and adhesion Give an example of each property?
Cohesion is an attraction between molecules of the same substance. Adhesion is attraction between molecules of different substances.
An example of cohesion is how you can cause water to extend out over the rim of a glass if you fill it carefully; the molecules are all pulling together.
An example of adhesion is when you dip a piece of paper towel into a glass of water. The water will climb up the fibers of the paper above the level of the water in the glass. The water is attracted to the paper.
Does caffeine ingestion affect blood test levels of serum glucose or LDL?
It affects triglycerides by increasing lipolysis and therefore free fatty acid/glycerol levels, don't think it affects LDL cholesterol.
Does Bank of America drug test you?
Yes. Generally places where you are dealing with large sums of money (banks) you are going to be drugtested.
it may and it may not because if you drink alot of water
it will be flushed from your system but if you dont it will still be there
What is Embadomonas intestinalis?
See Retortamonas intestinalis they are the same species of flagellates.
Does sexual reproduction produce genetic clones?
No, not at all. A clone produces offspring by sexual reproduction just like any other animal. A farmer or breeder can use natural mating or any other assisted reproductive technology, such as artificial insemination or in vitro fertilization to breed clones, just as they do for other farm animals.
If your husband and you have a positive why your baby is o positive?
f a husband and wife are are A positive and baby is O then it clearly depicts that both husband and wife are heterozygous and both have genotype "Ii and Ii" and as both have alleles "i" and when two "i alleles" combine they always result in blood group o having genotype ii

Infants have around 80ml per kilogram blood volume (although the range can be from 50-100ml'kg). This steadily drops to the adult values of 50-70ml/kg.
A 6 month old infant weighing approx 6 kg would have about 480mls of blood.
10mls taken out for blood samples would represent around 2% of the total blood volume
Repeated blood sampling in infants may result in loss of significant blood volume and so the reason why paediatric sampling bottles are used which require much smaller volumes than adults
Happy new year!

How do you determine the pKa value of an organic compound for HPLC method?
the organic compound three kind normal, acid and basic compound for acid compound the pKa from 3 to 5, normal pKa around 7 and basic compound more than 7
also you can know the kind of organic compound from structure that you can see acidic or basic grope like carboxylic acid or amine.
