Factor II / Prothrombin Mutation (G20210A)

G20210A Genetic Testing for Blood Clot Risk in Slough

What is the G20210A Mutation?
The G20210A mutation is a specific genetic change in the Factor II gene, which provides instructions for producing prothrombin — a protein essential for blood clotting. This mutation can lead to elevated levels of prothrombin in the blood, increasing the risk of abnormal clot formation.

Purpose of the G20210A Genetic Test
The G20210A genetic test is a laboratory test used to detect the presence of this mutation. It helps identify individuals who may be at a higher risk of developing blood clots, particularly conditions such as:

Deep Vein Thrombosis (DVT)

Pulmonary Embolism (PE)

Other thrombotic complications

Who Should Consider G20210A Testing in Slough?
This test is recommended for individuals in Slough and nearby areas such as Windsor, Langley, and Maidenhead who have:

A personal or family history of blood clots

Experienced a blood clot at a young age

Had unexplained or recurrent episodes of thrombosis

Been diagnosed with other clotting disorders

Pregnancy complications or are undergoing fertility treatments

Conditions Related to the G20210A Mutation
In addition to increasing the risk of thrombosis, the G20210A mutation may also contribute to or be associated with:

Factor II (prothrombin) thrombophilia

Factor II deficiency

Antithrombin III deficiency (when combined with other genetic risks)

How the Test is Performed
The G20210A test is a genetic screening conducted using a blood sample or cheek swab. The sample is analysed to determine whether one or both copies of the gene carry the mutation.

Private Thrombophilia Testing in Slough
Local clinics in Slough offer confidential and accurate G20210A testing, with no GP referral required. Testing is available as part of a full thrombophilia screen or a targeted genetic panel for clotting disorders.
