Factor V Leiden Mutation, DNA
A one-time genetic test for the most common inherited clotting disorder — a mutation that makes blood more prone to forming clots.
Genuinely important for two groups in this audience: anyone with elevated hematocrit from TRT or AAS (clot risk compounds), and women considering estrogen-containing contraceptives or HRT, where the combination substantially multiplies clot risk.
Optimal ranges, root causes, and the complete correction protocol — nutrition, supplements, lifestyle, hormones and peptides — plus 100+ other markers.

Would you feel it? Symptoms Factor V Leiden Mutation, DNA helps explain
People rarely search for a marker — they search for how they feel. These are the complaints where this marker is worth checking, and whether it is a first-line test or a follow-up once the obvious causes are ruled out.
Why your Factor V Leiden Mutation, DNA might be wrong
Most abnormal results are interference, not disease. These are the things that measurably move this specific marker — check them before you change anything. Each one says whether the number is wrong and should be repeated, badly timed and should be redrawn, or real with a cause worth explaining.
Fixed for life — but note the distinction from the FUNCTIONAL test: activated protein C resistance testing IS affected by anticoagulants, pregnancy and the pill. The genetic test is not.
If you are anticoagulated or pregnant, ask for the genetic test rather than the functional assay.
One copy raises clot risk modestly; two copies raise it far more. A report saying only 'positive' conflates them.
Get the zygosity, not just positive or negative.
Combined hormonal contraception carries markedly higher risk with Factor V Leiden, and it affects advice around surgery, pregnancy and long-haul travel.
A positive result is a conversation with a doctor — and it matters for your siblings and children too.
What Factor V Leiden Mutation, DNA means in combination
A single marker tells you a little. Combinations tell you the story — these are the named patterns this marker takes part in, and what each one points at.
One copy raises clot risk modestly; two copies raise it far more. A report saying only 'positive' conflates two quite different situations. It also changes contraception advice substantially, and matters around surgery, pregnancy and long-haul travel.
Get the zygosity. Combined hormonal contraception carries markedly higher risk with this variant — that is a prescriber conversation, and it matters for siblings and children too.
