Carrier Identification for Factor VIII and Factor IX Deficiency (Form NIBD)

Specimen Required

Patient & Mother 2 Vials Each EDTA+ Sodium Citrate

Fasting Required

Purpose of the Test

The carrier identification test for factor VIII and factor IX deficiency is used to determine whether an individual carries a genetic mutation that could cause hemophilia A or B. These are bleeding disorders that affect the body’s ability to form blood clots, and carriers are at risk of passing the condition on to their children.

When this test is required

The test may be requested for individuals with a family history of hemophilia A or B or for couples who are planning to have children and want to know if they carry the genetic mutations associated with these disorders.

What the Test Detects

The test analyzes the DNA of the individual to identify whether they have a genetic mutation associated with hemophilia A or B.

Preparation for the Test

No specific test preparation is needed, but individuals should inform their doctor if they are taking any medications that affect blood clotting.

Sample Requirements

The test requires a blood sample from the person being tested.

Additional Notes

Carrier identification tests can help individuals and couples make informed decisions about their reproductive options. If both partners are carriers of a genetic mutation associated with hemophilia A or B, there is a chance that their child will develop the condition. In these cases, couples may choose to pursue options like genetic counseling, in vitro fertilization, or adoption.
