DNA Thrombotic Risk
CA$195
What is thrombosis?
Thrombosis is when a blood clot forms inside a blood vessel and blocks the flow of blood through the circulatory system. Thrombotic risk refers to the likelihood of forming these dangerous blood clots.

Signs of a blood clot
Many factors contribute towards thrombotic risk, including a lack of mobility, smoking, obesity, surgery or injury, infections and disease, pregnancy, and hormonal changes.
However, “invisible” factors such as genetic changes that affect components of the blood clotting cascade also play a big role in your thrombotic risk.
Factor V Leiden mutation:
Factor V is a protein that promotes blood clotting. When it is not required, it is inactivated by protein C. The factor V Leiden mutation inhibits this inactivation, increasing the risk of abnormal blood clots.
Prothrombin G20210A mutation:
Prothrombin is another protein required for blood clot formation. In individuals carrying the G20210A variant in this gene there is an increase in prothrombin production, leading to an increased risk of abnormal blood clotting.
MTHFR mutations:
The MTHFR gene gives instructions to produce an enzyme involved in the conversion of folic acid to folate, which then helps convert homocysteine to methionine. Two MTHFR variants are linked to elevated homocysteine levels, known as hyperhomocysteinemia. Hyperhomocysteinemia increases the risk of abnormal blood clots.
Genetic Variants Analyzed
This test examines key genetic variants related to thrombophilia:
- F5 – Factor V Leiden mutation (1691G>A)
- F2 – Prothrombin mutation (20210G>A)
- MTHFR – Two mutations (677C>T and 1298A>C)
Each person inherits two copies of these genes—one from each parent. Possible genetic combinations include two normal copies (homozygous normal), two mutated copies (homozygous mutant), or one normal and one mutated copy (heterozygous). The specific combination of F5, F2, and MTHFR variants determines an individual’s risk for developing thrombophilia.
