What is the difference between anti-A and anti-B serum in blood typing tests?
Anti-A serum is used to detect the presence of A antigens on red blood cells, while anti-B serum is used to detect the presence of B antigens. This helps determine a person's blood type in blood typing tests.
What is a serum that will agglutinate in the presence of type B blood?
Anti-B serum will agglutinate in the presence of type B blood. This serum contains antibodies that specifically target the B antigen on the surface of red blood cells. When mixed with type B blood, agglutination will occur, resulting in the clumping of red blood cells.
Does the erythrocyte become haemolysed if the solution is still clear and how to explain this situation?
The erythrocyte can become haemolysed even if the solution(serum/plasma) is still clear. Visible check on haemolysed serum/plasma is not reliable as this is subject to the inspector. A haemolysed sample is defined when the concentration of the HGB in the serum/plasma is more than 100 mg/dl and not suitable for further laboratory testing. Therefore, erythrocyte in a clear serum/plasma may still be haemolysed, just that the level of haemolysed may be less than 100 mg/dl, and still suitable for laboratory testing.
How can tackle if serum ige level increased to 410?
A serum IgE test is to measure the level certain antibodies to screen for allergies. A high level count can indicate an allergy or a parasitic infection.
Why is serum preferred over plasma in serologic determinations?
serum is the preferred specimen for most chemistry, blood bank and serology test because proteins, such as fibrinogen, cause intererferences in the procedure or test. anticoagulant may also cause interferences which is present in blood plasma.
Which tube is anticardiolipin?
Anticardiolipin antibodies are typically detected using a blood test that measures the presence of these antibodies in serum. The test is often performed on a sample collected in a plain or serum separator tube (often a red-top tube). These antibodies are associated with antiphospholipid syndrome, which can lead to increased risk of blood clots. If you are undergoing testing, it's essential to follow your healthcare provider's instructions regarding sample collection and handling.
What is the color of human serum?
Human serum is typically a pale yellow color due to the presence of the protein albumin. The color may vary slightly depending on factors such as hydration level and diet but it is generally this light yellow hue.
Can blood glucose level falsely increased in lipemic serum?
Yes, blood glucose levels can be falsely increased in lipemic serum due to interference in some laboratory methods used to measure glucose levels. Lipemic serum contains high levels of triglycerides or fats, which can affect the accuracy of glucose measurements by some glucose assays. This interference can result in erroneously elevated glucose readings.
Why serum is used in germ tube test?
Serum is used in the germ tube test to provide nutrients and create an environment that promotes the growth and differentiation of yeast cells into hyphae. This helps in identifying certain pathogenic yeast species, such as Candida albicans, which produce germ tubes in the presence of serum.
Immunity gained through mothers milk or administration of an immune serum is described as what?
Immunity gained through mother's milk or the administration of an immune serum is described as passive immunity. This type of immunity occurs when antibodies are transferred from one individual to another, providing immediate but temporary protection against specific pathogens. In the case of mother's milk, antibodies like immunoglobulin A (IgA) are passed to the infant, while immune serum contains pre-formed antibodies that can help fight infections.
What is needed for Complement fixation test?
For a complement fixation test, you will need serum samples from the patient being tested, heat-inactivated complement serum, specific antigen-antibody complexes, an indicator system to visualize complement activity, saline or buffer solutions, and control samples. The test is used to detect the presence of specific antibodies in the patient's serum by measuring the level of complement fixation.
