Useful For Suggests clinical disorders or settings where the test may be helpful

Genetic confirmation of a factor VII deficiency diagnosis with the identification of a known or suspected pathogenic alteration in the F7 gene


Carrier testing for close family members of an individual with a factor VII deficiency diagnosis


This test is not useful for prenatal diagnosis.

Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request

This test detects pathogenic alterations in the F7 gene to delineate the underlying molecular defect in a patient with a laboratory diagnosis of Factor VII deficiency (F7D), a rare bleeding disorder.


The gene target for this test is:

Gene name (transcript): F7 (GRCh37 [hg19] NM_000131)

Chromosomal location: 13q34

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

The clinical workup for factor VII deficiency (F7D) begins with coagulation testing consisting of coagulation factor VII assay (see F_7 / Coagulation Factor VII Activity Assay, Plasma).


Genetic testing for F7D is indicated if:

-Factor VII activity is reduced (less than 65% of normal)

-Acquired causes of FVII deficiency have been excluded
