Iron deficiency diagnosis in 2026:
• Ferritin ≤20 ng/mL: children 9 mo–4 y
• ≤30 ng/mL: most adults
• ≤50 ng/mL: selected higher-risk patients
• In inflammation: use ferritin + TSAT; consider TSAT <20% or ferritin <100 ng/mL

Normal Hb/MCV does not exclude iron deficiency

SERUM IS NOT SIMPLY PLASMA MINUS FIBRINOGEN

Plasma is the liquid portion of anticoagulated blood. Serum is the liquid that remains after blood has clotted.

During clotting, the liquid phase is remodeled:

I saw a patient last week with a hemoglobin of 4.3 g/dL.

Sitting comfortably.
Normal oxygen saturation.
Normal blood pressure.
Heart rate in the 70s.

How can the body tolerate such a profound reduction in oxygen-carrying capacity?

A physiology thread. 🧵

WHAT DOES COPPER HAVE TO DO WITH IRON?

More than I realized.

Copper-dependent ferroxidases help move Fe from cells → transferrin → erythron.

So copper deficiency can impair Fe delivery even when Fe is present.

And that’s only one way copper deficiency causes anemia.

WHY DOES THE MENTZER INDEX WORK?

MCV/RBC count <13 → think thalassemia trait
MCV/RBC count >13 → think iron deficiency

Easy to memorize.

But there's physiology hiding inside the formula.

Here's a thought experiment 👇

Google just released free 2-hour course on full agent engineering: 1 prompt → agent teams → loops → graphs from 0% to 100%:

10% → 38:46 - build your first agent
30% → 54:46 - connect MCP tools
55% → 1:12:43 - Loop engineering: 4 ways to run agents
70% → 1:20:57 - Graph engineering
100% → 2:22:31 - the full system that works while you sleep

most people build one agent and stop there - this is the full path to a system that runs without you from scratch

watch it today - then read the full graph engineering playbook below ↓

Andrew Ng just released a 1-hour course on building multi-agent systems from scratch:

• 00:00 - Introduction to agentic AI
• 03:07 - Building your first graph from scratch
• 14:00 - Connecting tools, memory, and context
• 23:00 - Building with Google ADK
• 01:06:03 - Why graphs are the future

In 1-hour he shows exactly how to build an agentic knowledge Graphs that improves itself.

Most people are still doing all of this by hand.

Watch the session, then save the guide below.
