Why Blood Testing Is Essential Alongside Methylation Genetics
Genetic testing offers valuable insight into how someone might process nutrients — but it doesn’t tell us what’s actually happening right now. Genes are like the blueprint or potential, but they don’t operate in isolation. As the saying goes: genetics loads the gun, but the environment pulls the trigger.
Someone may carry a slow MTHFR variant — but are they a 6-foot sumo wrestler with high nutrient demands, or a 4-foot-2, slightly built woman with a minimal intake and lower metabolic needs? A genetic report can’t tell us that. It also doesn’t reveal whether someone is living on fast food or following a nutrient-rich, balanced diet. Genes show us the potential — but they don’t show us the current reality.
That’s why, when it comes to making personalised, effective nutrition decisions — particularly around methylation — it’s essential to combine functional blood testing with genetic results.
When we look at methylation-related genes like MTHFR, MTR, MTRR, COMT, and others, we gain a better understanding of how a person might convert folate, process B12, recycle homocysteine, or clear neurotransmitters. But what we don’t see is:
That’s where blood testing becomes crucial. Measuring markers such as:
Put simply, genetics tells us what the body is capable of, but blood testing shows us what the body is actually doing.
OPTION 1 – Attending the lab in central London for your blood draw – Recommended
13 Blood markers included
Please note: If you choose the option to attend the Central London lab, you must also select the COMPREHENSIVE BLOOD DRAW add-on below.
Once your order is placed, the kit will be sent to your home (for you to take to the lab in central London) and the lab will contact you directly to arrange your blood draw appointment. You are responsible for paying the blood draw fee directly to the lab at the time of your appointment.
OPTION 2 – Arranging your own phlebotomy service
11 Blood Markers included, Excluding – Red Blood Cell Folate and Homocysteine – As these samples are time sensitive and cannot be posted. The Zinc marker can be reported providing the blood sample is centrifuged at the time of collection and returned via the next day delivery service included with the test kit. If the sample is not centrifuged the zinc marker will not be reported.
The cost of the test is the same whether you choose option 1 or option 2. There is no deduction available for the excluded markers.
