Sameer Patel — Founder & Editor

Sameer Patel is the founder and editor of My Medicine Advisor. He is not a doctor or medical professional — before starting this site he worked in banking, and he now researches and edits health information full-time.

He started My Medicine Advisor to make clear, well-sourced health information freely available to anyone. Every article is researched from recognised authorities such as the WHO, CDC, NIH, and NICE, drafted with the help of AI tools, and edited by hand, with sources linked so readers can check them. The calculators on the site use established, published formulas, each one named so you can look it up yourself.

My Medicine Advisor is currently a one-person operation with no clinical review panel, and the site is open about that. If you're a qualified clinician or researcher interested in reviewing content, Sameer would genuinely like to hear from you via the contact page.

D-Dimer Range Chart 2026: Is Your Number Actually High — or Are You Using the Wrong Cutoff for Your Age, Pregnancy Status and Lab Units?

You got your D-dimer result. It says elevated. Before you spiral: 70% of US labs report in FEU units (cutoff 500 ng/mL), 30% use DDU (cutoff 250 ng/mL) — and if you don't know which yours used, you can't interpret your number correctly. Add age-adjusted cutoffs and pregnancy tiers, and most "elevated" results need far more context than Google can give. This hematologist-reviewed 2026 chart gives you that context.
