How do I know if I have Haemophilia?

TL;DR: Haemophilia is a rare genetic bleeding disorder characterized by a deficiency in clotting factors, usually diagnosed through specific blood tests that measure factor VIII or factor IX levels. If you notice persistent, unexplained bruising, prolonged bleeding from minor cuts, or frequent nosebleeds, you should consult a hematologist for a formal diagnostic evaluation.

What are the early signs and symptoms of Haemophilia?

The hallmark of Haemophilia is difficulty with blood clotting, which often manifests differently depending on the severity of the condition. In individuals with mild Haemophilia, symptoms might only appear after significant trauma or surgery. However, those with moderate or severe forms may notice early signs such as unexplained bruising, prolonged bleeding after dental procedures, or bleeding into joints (hemarthrosis) that causes swelling, warmth, and pain. Because Haemophilia affects the body’s ability to form a stable clot, even minor injuries can lead to bleeding that lasts much longer than expected.

How can I recognize patterns that might indicate Haemophilia?

When assessing your health for potential Haemophilia, look for patterns that deviate from normal healing. While everyone bruises occasionally, individuals with this condition often report bruising that is unusually large, firm to the touch, or occurs without a clear memory of an injury. Keep a log of your "bleeding history" to share with a physician; note the duration of bleeding from small nicks, the frequency of spontaneous nosebleeds, and any history of heavy menstrual bleeding or post-surgical complications. It is important to distinguish between normal variation—such as a small bruise from a bump—and the persistent, deep-tissue bleeding often associated with Haemophilia.

Which medical tests are used to diagnose Haemophilia?

If you suspect you have Haemophilia, your primary care physician should refer you to a hematologist. The diagnostic process involves specific blood panels designed to measure the activity of clotting factors. These tests typically include:

• Complete Blood Count (CBC): To check overall blood health and platelet counts.


• Activated Partial Thromboplastin Time (aPTT) Test: Often prolonged in those with Haemophilia.


• Prothrombin Time (PT) Test: Usually normal in Haemophilia, helping to rule out other conditions.


• Clotting Factor Assays: The definitive tests that measure the specific levels of Factor VIII (for Haemophilia A) or Factor IX (for Haemophilia B).

When should I seek urgent medical evaluation?

Certain symptoms associated with Haemophilia require immediate emergency care. You should seek urgent medical attention if you experience signs of internal bleeding, such as a severe headache, persistent vomiting, neck stiffness, or sudden vision changes, as these can indicate intracranial hemorrhage. Additionally, any significant injury to the head, neck, or abdomen in a person with known or suspected Haemophilia warrants an immediate trip to the emergency room.

How can I advocate for myself in a clinical setting?

If you feel your concerns are being dismissed, remember that you are the expert on your own body. If your physician is hesitant to order specialized coagulation studies, clearly state your concerns regarding your bleeding history and request a referral to a hematology specialist. You may also find it helpful to connect with the 334 members of the DiseaseMaps.org community who are living with Haemophilia, as their shared experiences can provide guidance on how to navigate the diagnostic process effectively. Bringing a written summary of your symptoms to your appointment can also help ensure your concerns are taken seriously.

Next steps

• Consult a hematologist to discuss your symptoms and request specific clotting factor assays.


• Keep a detailed diary of all bleeding events, including the duration and the cause, to show your doctor.


• Connect with the DiseaseMaps.org community to learn from others who have navigated the diagnosis of Haemophilia.


• Review your family history to see if any relatives have had unexplained bleeding disorders, as Haemophilia is an X-linked genetic condition.
