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.
What Goes Into an A1C Goal for Someone Over 65
A1C targets loosen for some older adults, not all — among those on insulin or a sulfonylurea, 26% to 40% meet the research definition of overtreatment.

A1C in pregnancy is not one answer. The same test is asked four different questions across a pregnancy — and none of them is gestational diabetes.
Where Your Point-of-Care A1C Was Run Changes What It Means
Point of care A1C results are real, and whether one can diagnose depends on two separate permissions: the device's clearance and the site's certificate.
A Clear Map of What A1C Can’t Diagnose
What A1C can't diagnose is four unrelated failures — and four authoritative sources draw that boundary in four different places.
The Fructosamine Test Measures Weeks, Not Months
A fructosamine test can be thrown off by a vitamin C supplement — major laboratories ask patients to hold it for 24 hours first.
What an A1C or OGTT Can and Cannot Find
A1C or OGTT: pregnancy and a short list of blood conditions turn the choice into a rule.
Outside those, the A1C is usually what arrives.
The Clear Difference Between a False High A1C and a Real One
A false high A1C has two possible inputs, and only one is your blood sugar. Which anemia you have decides which way the number actually moved.
What Sickle Cell Trait Does to an A1C Result
Sickle cell trait and A1C: the method is usually not the problem. A normal result is, and
closing that gap takes one extra question at your next visit.
What a Very High A1C Result Actually Sets in Motion
Very high A1C is the guideline's own phrase for a result above 10% - the point where insulin should be considered, not a separate severe tier.
