@ILoveBlueBell @ILoveBlueBell I grew up in Brenham but now live in STL- glad my kids will now get to enjoy the ice cream I grew up on! Now, If you could please just send some Dairy Bar and/or Whataburger our way...

@kurt13warner Shorter=lower center of gravity= harder to tackle (all else being equal)

@_MLFootball @DomClare @vikesinsider @VikesCentral @VikingNations @nacholeber @johnkriesel @DustBaker @Yfz84 @ajv @BarstoolMSU Wow, a normal person had to pay for tickets like a normal person. So impressive

@acweyand @Gleason4plus5 I think what you desire are called "clinical decision limits". These are thresholds associated with specific outcomes, rather than concentrations from "normal" individuals. This is what we use for lipids, HgbA1c, etc. Reference change values are another useful alternative.

@joerogan Sounds like he's asking you to put your $$where your mouth is

@PGH_PharmD Units?

@SteveCurryMD 1. Ferrochetalase

@hyderabaddoctor MMA and total homocysteine are better biomarkers of B12 deficiency than serum/rbc B12 . This is because you can have normal blood concentrations of B12 but low concentrations at the tissue level. The functional biomarkers (MMA/tHCY) are more sensitive than B12.

@basophil_brett @LJPelkey @NicholasELarkey @mark_girton Glycation since it is non-enzymatic (glycosylation is enzymatic)

@neely615 No no, it was a positive conversation. I won't ruin this poll by disclosing how you convinced me, but I'll say you had a strong justification (IMO).

[Stephen Roper @stephen_roper]

@neely615 I still remember our conversation about this years ago. You would be proud to know that I have only used quantify/quantification ever since.

@SallyMaelstrom Pancreatitis, Glycerol Kinase deficiency (artifactual TG increase), Lipoprotein lipase/ApoCII deficiency, etc. Any idea of why they ordered a lipid panel on a newborn? This may provide clues to the origin of hyperTG.

[Stephen Roper @stephen_roper]

@neely615 Absolutely- many fond memories with Click!

@mlpaoceo @MLPAOnews But we are talking about this- see the American Association of Clinical Chemistry Annual Scientific Meeting 2022 session 33109: https://t.co/nLOFRw067Q

I discovered the best positive feedback loop today!

@DrReddyGI @ebtapper @AtoosaRabiee @GI_Pearls @AASLDtweets A little late to the party here, but my guess would be analytical imprecision. I'd ask the lab to repeat the specimen and review QC for Bili
