Biomarker reference
The inflammatory, methylation and micronutrient signals that sit underneath brain fog and a short fuse.
This group measures the inflammatory, methylation and micronutrient signals that sit underneath symptoms people usually attribute to overwork — brain fog, a short fuse, poor recovery, sleep that stops restoring. None of these markers diagnoses a disease. What they do is distinguish between a person who is simply busy and a person whose physiology is carrying a measurable burden, which is a distinction no symptom questionnaire can make. hs-CRP quantifies low-grade inflammation, the kind that tracks with cardiovascular risk and insulin resistance in people who feel entirely well. Homocysteine reads B-vitamin sufficiency functionally, often revealing a shortfall before the vitamin levels themselves look abnormal. The omega-3 index describes membrane composition built up over months of diet. Together they explain a substantial share of what gets written off as stress.
No marker in this group means much on its own. Cognitive load & stress covers 14 of the measurements in the Peak Brain panel, and a physician reads them as a pattern — one value at the edge of a reference range means something quite different depending on what the others are doing.
hs-CRP is a high-sensitivity measurement of C-reactive protein, a substance the liver releases in response to inflammation.
Homocysteine is an amino acid produced continuously as the body processes methionine from dietary protein.
The omega-3 index measures EPA and DHA — the two long-chain omega-3 fatty acids — as a percentage of the total fatty acids in red blood cell membranes.
These markers are included in the panel and read alongside the ones above. They have no standalone reference page, because outside the context of a full panel there is little useful to say about them individually — and a page that exists only to fill a URL is worse than no page.
Reviewer assignment follows speciality. Pages in this group are assigned to Dr. Shahir Asfahan (MD, DM, DNB, FICS) and Dr. Alfia Kaki (MD, PGC) and Dr. Irfan Shaik, and each page carries a byline naming its reviewer and the date of review.
No. There is no blood test for burnout, and any claim otherwise should be treated sceptically. What these markers do is identify physiological contributors — inflammation, B-vitamin shortfall, poor omega-3 status — that produce overlapping symptoms and that are correctable once identified.
Usually not immediately. A single raised value is most often explained by a recent infection, and anything above 10 mg/L generally reflects an acute process rather than chronic inflammation. Repeat it two to three weeks after full recovery; a persistently raised value with no obvious cause deserves a physician's view.
B12, folate and B6 reliably lower homocysteine, but the right response depends on which one is short and why. Self-supplementing without knowing can mask a B12 deficiency while leaving neurological damage progressing, which is why the underlying vitamins are measured rather than the marker treated directly.
The programme
Peak Brain draws a full blood and urine panel at your home, has a licensed physician read every marker together rather than one at a time, and turns what they find into a ranked 90-day protocol with a retest at the end.
