1/3 I CHANGED MY MIND ABOUT RETICULOCYTES For years, my rule was simple: ARC ≥120 × 10⁹/L? Regenerative. Stop there. No grades, just pass/fail. I no longer think that's quite right. 4.9K views · 53 likes · 6 reposts · 1 replies Open on X →
@WilliamAird4 Persistent unexplained high B12 shouldn't be dismissed just because the patient 'looks healthy.' We see the same reflexive dismissal of abnormal labs in ME/CFS patients constantly. 1.9K views · 0 likes · 0 reposts · 1 replies Open on X →
3/4 Think about low B12. Hematologists see B12 deficiency when it causes anemia or other cytopenias. We generally don't see patients whose B12 deficiency manifests only as neurologic disease or chronic atrophic gastritis. Why should high B12 be different? 3.1K views · 6 likes · 1 reposts · 1 replies Open on X →
4/4 A persistently elevated B12 may warrant evaluation. But hematology should get involved when there is evidence of a hematologic disorder, not simply because the B12 is high. 2.8K views · 24 likes · 3 reposts · 6 replies Open on X →
WHO OWNS A HIGH B12? A referral to my clinic last week prompted me to ask: An otherwise healthy patient has a persistently elevated vitamin B12 level. When should hematology get involved? 768 people voted. 21.5K views · 62 likes · 5 reposts · 3 replies Open on X →
2/4 Results: • 62%: If CBC/smear is abnormal • 22%: If no cause is found • 11%: All such patients • 6%: Only if B12 is very high I agree with the majority. 3K views · 5 likes · 1 reposts · 1 replies Open on X →
SPLENIC INFARCTION A splenic infarct tells you what happened. It does not tell you why. Embolism? In-situ thrombosis? APS or MPN? Sickling? Babesiosis or malaria? Venous outflow obstruction? 5.2K views · 52 likes · 7 reposts · 1 replies Open on X →
