In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder. Because it is unlikely that females will have two altered copies of this gene, it is very rare for females to have hemophilia.
Liver Function Tests. For blood testing a syringe with a fine needle is used to remove a small amount of blood from a vein in your arm. You should only feel a tiny pinprick as this done. The sample can be taken by your GP or a nurse at your local clinic, or by hospital staff. It will then be sent to a laboratory to be tested.
Liver Function Tests. Liver function tests measure various chemicals in the blood made by the liver. An abnormal result may indicate a problem with your liver and may help to identify the cause. Further tests may be needed to clarify the cause of your liver problem. The liver is in the upper right part of your tummy (abdomen).
