Hemophilia Screening Test – Diagnosing Bleeding Disorders
Hemophilia is a genetic bleeding disorder that impairs the blood’s ability to clot, leading to excessive bleeding even after minor injuries. The Hemophilia Screening Test is crucial for diagnosing this condition, which is typically inherited and affects males more than females. Early diagnosis can help manage the disorder effectively and prevent complications such as spontaneous bleeding or joint damage.
Indications for Hemophilia Screening Test:
● Unexplained prolonged bleeding: After injuries, surgeries, or dental procedures.
● Family history: If there is a known family history of hemophilia, genetic testing is recommended, especially in males.
● Abnormal bruising: Unexplained large bruises or swelling without trauma.
● Spontaneous joint or muscle bleeds: Frequent joint or muscle bleeds without obvious injury may indicate hemophilia.
Methods to Diagnose Hemophilia:
● Activated Partial Thromboplastin Time (aPTT): This test measures the time it takes for blood to clot. Prolonged aPTT may indicate a bleeding disorder such as hemophilia.
● Factor VIII or Factor IX Activity Test: These tests measure the activity of clotting factors. Low levels of Factor VIII indicate Hemophilia A, while low Factor IX levels indicate Hemophilia B.
● Genetic Testing: Can confirm mutations in the Factor VIII or Factor IX genes, which are responsible for the bleeding disorder.
Normal Range:
● Factor VIII (Hemophilia A): 50%–150% activity.
● Factor IX (Hemophilia B): 50%–150% activity.
● aPTT: Normal clotting time (generally around 30-40 seconds depending on the laboratory).
Abnormal Test Significance:
● Low Factor VIII or IX activity: Indicates Hemophilia A or Hemophilia B.
● Prolonged aPTT: Suggests a clotting factor deficiency and may require further testing to confirm hemophilia or other bleeding disorders.
Management:
● Clotting factor replacement therapy is the standard treatment for hemophilia. This involves infusions of Factor VIII (for Hemophilia A) or Factor IX (for Hemophilia B) to restore normal clotting.
● Gene therapy is emerging as a potential long-term solution for hemophilia treatment.
Price in India:
● Approx. ₹3,000 – ₹5,000 for screening tests like aPTT and factor activity levels.
FAQs
What are the signs that I may have hemophilia?
Frequent, unexplained bruising, prolonged bleeding after cuts or injuries, and spontaneous joint or muscle bleeds.
Is hemophilia only a genetic disorder?
Yes, hemophilia is an X-linked recessive disorder, which means it is inherited and more common in males.
Disclaimer:
Hemophilia screening tests should be interpreted alongside clinical symptoms. A positive result needs to be followed by genetic counseling and hemophilia treatment for proper management.
