MTHFR Genetic Testing



An elevated homocysteine level is known to be an independent risk factor for ischemic stroke, thrombotic and cardiovascular diseases. Homocysteine is an amino acid synthesized by the body. In the presence of adequate levels of Folate, vitamin B6 and vitamin B12, homocysteine is either metabolised to cysteine or methionine in a process called methylation. A deficiency in any one of these b-vitamins can cause homocysteine levels to rise.


The MTHFR gene produces an enzyme that helps process folate and regulate homocysteine in the body. Folate is a critical nutrient involved in methylation, and also in DNA synthesis and amino acid metabolism. Impaired folate metabolism due to MTHFR enzyme inactivity or a low folate level results in elevated plasma homocysteine.


Research has shown that many individuals may be at risk of methylation insufficiency due to reduced MTHFR enzyme function.

The test includes the two SNPs known to affect MTHFR function are the C677T and A1298C mutations. It is not uncommon for some individuals to have both MTHFR variants, which can also lead to depression.

We will send you the test kit with 3 buccal swabs. You need to send it back to Invivo Clinical via guaranteed 1 pm next day delivery at your own cost. The results come back to us and we will post them into your patient portal.

If you like to discuss the results we can do this in a separate consultation with Dr Frey.
