Diagnostic Tests for Hemophilia Your Doctor may Order
Hemophilia News Today shares what many are not quite aware of about hemophilia. It is a bleeding disorder wherein blood clotting is messed up. This means, instead of your body naturally closing a wound with a scab, there would be no clotting at all. Some of the bleeding symptoms may be similar in hemophilia A and B, the underlying causes are different. This is why it is important to visit the right type of diagnostic clinic in Cebu for the appropriate medical exam in Cebu and lab tests to be able to determine the type of hemophilia so your doctor would be able to give you the appropriate therapy and treatment.
Here are the diagnostic tests your doctor would advise you to take:
For hemophilia screening tests, it would require blood, to determine if the blood is clotting properly. Types of screening tests are complete blood count (CBC), activated partial thromboplastin time (APTT) test, prothrombin time (PT) test, and fibrinogen test.
- Complete blood count (CBC) – This measures the following:
a. amount of hemoglobin, the red pigment that carries oxygen within the red blood cell b. the size and number of red blood cells (RBCs)
b. number of white blood cells and platelets in the blood
- CBC results are normal in people with hemophilia, but there is a decrease in hemoglobin and RBCs with heavy or prolonged bleeding.
- Activated partial thromboplastin time (APTT) test – This measures the delay in blood clot formation and the clotting ability of factors VIII, IX, XI and XII. If any of the clotting factors are too low, it takes longer for the blood to clot. Patients with hemophilia A or hemophilia B show a longer clotting time in this test.
- Prothrombin time (PT) test – This measures the time it takes for the blood clot to form. It measures the clotting ability of different set of factors I, II, V, VII, and X. If any of these factors are too low, it takes longer than normal for the blood to clot. The results of this test will be normal for patients with hemophilia A or hemophilia B since these conditions are caused by defects in factors VIII and IX, respectively.
- Fibrinogen test – Fibrinogen, known as clotting factor I, assesses the patient’s ability to form a blood clot. This test is performed along with other blood clotting tests or when a patient has an abnormal PT or APTT test result.
If you are a hemophiliac and you are pregnant, there is a prenatal testing for hemophiliac expectant mothers. A pregnant hemophilia carrier can get early diagnosis for her unborn baby as early as 12 weeks into their pregnancy. The diagnostic test is done through chorionic villus sampling (CVS) or through fetal blood sampling at 18 weeks or more.
