Factor Deficiency : Factors VII and VIII

Factor VII and Factor VIII are clotting factors in the blood that play a crucial role in the coagulation cascade. Deficiencies in these factors can lead to bleeding disorders.

Sample Type: The test requires a small blood sample, typically obtained by drawing blood from a vein in your arm using a needle.

Normal Range: The normal range for Factor VII and Factor VIII levels can vary depending on the specific laboratory and the reference values they use. Generally, the normal range for Factor VII is around 50 to 150% activity, while the normal range for Factor VIII is around 50 to 200% activity.

Factor VII and Factor VIII deficiencies can be hereditary or acquired. Hereditary deficiencies are usually present from birth and are caused by genetic mutations. Acquired deficiencies can occur due to various factors such as liver disease, vitamin K deficiency, certain medications, or autoimmune disorders.

Individuals with Factor VII or Factor VIII deficiency may experience symptoms such as easy bruising, nosebleeds, excessive bleeding from wounds, or prolonged bleeding after surgical procedures.

If a deficiency in Factor VII or Factor VIII is suspected, a blood test can be performed to measure their activity levels. If the levels are below the normal range, further evaluation and additional tests may be needed to determine the underlying cause and appropriate management.

It’s important to consult with a healthcare professional for proper interpretation of your Factor VII and Factor VIII test results and to discuss any necessary steps or treatments based on the findings.
