A new hematology guideline moves the ferritin cutoff for iron deficiency in adults from 15 to 30 ng/mL. What ferritin measures, why men run low and what to do about a low result.
How long to fast before a blood test: a JAMA Internal Medicine study of 101,148 patients found 8 hours covers glucose, and fasting past 12 hours made no meaningful difference.
Pelacarsen missed its primary endpoint in the Lp(a)HORIZON trial. Here’s what’s actually known, what two doctors think happened, and why I’m putting my own effort back into LDL and ApoB instead of waiting on an Lp(a) drug.
I do not take a statin. I got my ApoB to 59 with about 170 pounds of weight loss and a generic ezetimibe that runs me twenty dollars a month, so when a big statin trial reads out I have nothing invested in the answer. I have also written here about why most of the
Updated September 16, 2026 with the revised label now posted to DailyMed. The FDA approved Mounjaro today to lower the risk of heart attack, stroke, and cardiovascular death in adults with type 2 diabetes who are at high risk for those events. That is a real expansion, and for a lot of people it is

By every framework I can find, a 60 is a
An ApoB of 90 mg/dL is the most average result an American adult can get. ApoB is in effect a particle count: every particle that can push cholesterol into an artery wall carries exactly one copy of it. In the National Lipid Association’s percentile table for untreated US adults, 90 is the 50th percentile. Whether
My first ApoB result was 95 mg/dL, in May 2025. Labcorp flagged it high, because Labcorp’s reference range tops out at 90. Cleveland Clinic publishes a normal range for men of 66 to 133, so the same tube of blood at a different lab would have come back with no flag at all. Whether my
I priced one standalone ApoB test at thirteen services on the same day. The advertised prices start at $11; the checkout totals start at $19.
