Results you can feel and see
“I liked that it wasn't just another kit you do once and forget about. The test showed me where I was starting, and the detox pack made it feel like I was actually moving the needle. It gave me some peace of mind.”
“The results were kind of a wake-up call. Having the supplements right there made it easy to do something about it instead of just worrying. I like that it takes the guesswork out.”
“What made this different was having both the numbers and the next step. I re-tested after a month and my microplastics load went from moderate to low. That was the first time I've seen clear proof something like this worked for me.”

What biomarkers do you test?
Blood biomarkers offer a crucial understanding of your metabolic health and nutritional condition, assisting in identifying potential nutrient deficiencies and disease risk. At Keyspan, we examine the following:
Baseline test for men:
Glucose, Hemoglobin A1c, Cholesterol, HDL, LDL, Triglycerides, ApoB, Calcium, Vitamin D, Testosterone, Cortisol, Albumin, Magnesium, Folate, Vitamin B12, RDW, Iron, Hemoglobin, Potassium, CRP, Homocysteine, GGT, AST, ALT.
Baseline test for women:
Glucose, Hemoglobin A1c, Cholesterol, HDL, LDL, Triglycerides, ApoB, Calcium, Vitamin D, Testosterone, Cortisol, Albumin, Magnesium, Folate, Vitamin B12, RDW, Iron, Hemoglobin, Potassium, CRP, Homocysteine, GGT, AST, ALT, Estradiol and TSH (Thyroid).
Initial blood draws are collected at home (or a place of your choosing) with a mobile phlebotomist. At the 6 month mark, we do another followup blood draw to fine tune the plan.
Is Keyspan comprehensive for women & men’s health?
We cater to the distinct metabolic and hormonal differences between men and women, this way plans and recommendations can be further tailored to the individual based on their unique physiology.
What’s Keyspan’s methodology for ranges? How does this differ from what I might find elsewhere?
Our method for ranges is to shift the range of western medical “normal” to a more functional range, flagging on-edge biomarkers as opportunities to prevent reds. Western medical range samples are taken from the majority, not from the healthy.
Why is my first month $299 if I live in NY/NJ/RI?
Due to state-specific costs, customers in NY, NJ, and RI pay a one-time additional fee during their first month. This fee covers additional regulatory and logistical costs. After the first month, your subscription is the standard $199/month.
