What Will Online MTHFR Gene Testing Reveal?

Genetic testing can be incredibly useful when done properly. Here’s how to get online MTHFR gene testing.

This type of testing is ideal for proactive individuals who want to know if they have inherited the common MTHFR genetic blueprint.

The Methylenetetrahydrofolate Reductase (MTHFR) Enzyme

The methylenetetrahydrofolate reductase (MTHFR) gene contains the genetic code to produce the MTHFR enzyme. This enzyme sparks activity within all cells, and plays an integral role in activating folate.

It’s likely you already know folate is an incredibly important B-vitamin that is necessary at every life stage, from early development in the womb through to adulthood. A glitch with proper folate metabolism increases the risk of developing a range of medical conditions.

Here’s what you need to know about testing.

The MTHFR Gene Test

The MTHFR test checks the two most common genetic markers —> C677T and A1298C. The lab results are either POSITIVE or NEGATIVE.

If NEGATIVE, the C677T and A1298C mutations were not detected. If POSITIVE, the report will use the terms heterozygous and homozygous. Let me explain the important differences between these two terms.

It’s possible to inherit a copy of the MTHFR gene mutation from one, or both parents (which does not change during your lifetime). If you are heterozygous you have one copy of the gene mutation from one parent. If you are homozygous you have a double mutation – a copy has been passed down by both parents.

Could You Have A Faulty MTHFR Gene – And Not Know It?

Finding it difficult to get the tests you want? Direct-to-consumer testing is a great option for those who want to find out if they have the MTHFR gene mutation.

Online MTHFR Gene Testing in Australia

In Australia? i-screen, Australia offer a confidential and affordable online testing service.

No referral is necessary and there are three simple steps to getting the MTHFR Check. Firstly, set up an online account and order the MTHFR Check. This measures the two main gene variants known as C677T and A1298C. Once the pathology form is emailed to you head to your local collection center to have your blood sample taken. The results should be available in 7-10 days and will be published on your online dashboard.

i-screen advise the MTHFR Check currently costs AUD$69.00. You can find out more on the i-screen, Australia website.

How To Get MTHFR Gene Testing In The USA

If you are in the USA True Health Labs provide direct access to laboratory testing. This company have created the MTHFR DNA Analysis.

Knowing this specific genetic marker helps you live better as it helps you create a highly personalized treatment plan. Find out more on the True Health Labs website.

In Summary

There’s three important points to consider if you have a positive MTHFR result.

Your genes are not hard-wired to cause illness.

The emerging science of epigenetics tells us that inherited genetic traits are not hardwired to create illness. Your diet and environment have a huge impact on gene expression. This means there’s so much you can do to optimize your health.

Be aware, if you have a positive MTHFR gene status you should avoid folic acid in processed foods and dietary supplements.

Folate supplements have evolved and methyl folate (not folic acid) is best for those with a positive MTHFR status.

Lastly, it can be all too easy to blame a host of symptoms on a positive MTHFR test result.

For this reason, consider seeking out a healthcare practitioner who understands MTHFR issues, especially when you have a diagnosed thyroid disorder. YES! Having a faulty MTHFR gene matters to thyroid health.
