What is Bassos auto abs blood test?

Bassos auto ABS test was formerly known as the Bassos autoagglutinin test. It detects if a patient has the anti-A1 autoagglutinin present in the serum or plasma. The anti-A1 is one of the many autoagglutinins that can interfere with testing by causing autoagglutination of red blood cells (RBCs).

The Bassos auto ABS blood test is typically performed as part of an antibody screen, which is a panel of tests used to identify antibodies in a person's blood that could potentially react with transfused blood. It may be used in cases of suspected transfusion reactions, autoimmune hemolytic anemia, or when patients have a positive direct antiglobulin test (DAT).

Procedure

The Bassos auto ABS blood test is performed by mixing the patient's serum or plasma with a panel of A1 and A2 red blood cells. If the patient has anti-A1 autoagglutinin, it will cause the A1 red blood cells to agglutinate (clump together). The A2 red blood cells will not be affected.

Interpretation

A positive Bassos auto ABS blood test result indicates that the patient has anti-A1 autoagglutinin in their blood. This can be caused by several conditions, including:

- Autoimmune hemolytic anemia is a condition in which the body's immune system attacks its healthy RBCs.

- Transfusion reactions can occur when a person receives a blood transfusion that is incompatible with their blood type.

- Other medical conditions, such as certain infections, cancers, and autoimmune diseases, can also cause anti-A1 autoagglutinin to develop.

However, it's important to note that a positive Bassos auto ABS blood test result does not always indicate a medical problem. In some cases, it may be a temporary finding that resolves on its own.

Therefore, a positive Bassos auto ABS blood test result should always be interpreted in the context of the patient's individual situation and overall health. Additional testing may be necessary to determine the cause of the autoagglutinin and to rule out any underlying medical conditions.
