The Coombs probe is a type of blood test that evokes the presence of specific antibodies that attack red blood cells, causing their destruction and that can lead to the development of a type of anemia called hemolytic anemia.
There are the main types of this hotfix, including:
- In addition to anemia.
- This test can also help identify other diseases that affect blood cells such as leukemia.
- Lupus.
- Mononucleosis.
- And fetal erythroblastosis.
- Also known as hemolytic disease in a born child.
- As well as identify the risk of transfusion reactions.
The Coomb test is performed from a blood sample, which must be obtained in the clinical laboratory, the blood is obtained in the laboratory, where direct and indirect Coombs will be tested, depending on the target.
In the direct Coombs test, the Coombs reagent is added to the patient’s blood, allowing the visualization of antibodies that may be related to erythrocyte. As the indirect thrust of Coombs bursts, blood is obtained and centrifuged separating plasma erythrocytes, which contain antibodies. In plasma, “pre-marked” red blood cells are read with antibodies to check for autoantiantibodys present in the plasma and therefore in the patient’s blood.
No preparation is required to treat the Coombs problem, however some medicines may interfere with the outcome, so it is important to inform your doctor of its use so that you can focus on its suspension.
The result of the Coombs test is negative when there are no antibodies that cause the destruction of red blood cells, so it is considered a normal result.
However, when the result is positive, I mean there is anti-blood in the blood, because if the result was positive in the direct Coombs problem it means that the person might have a disease like:
In the case of the indirect Coombs problem, the positive result means that the person has an antibody that can cause clots when receiving another type of blood, so be careful when transfusion of blood.
In all cases, it is always important that the result be evaluated by the doctor who requested it and that certain history of the person can change the outcome.
