Dosing arithmetic, reconstitution maths, and how people use the tracker.
Collected from the threads in this category over the last few months. 1. Treating syringe units as a mass. They're a volume marking. Meaningless without a concentration. 2. mg/mcg…
Written out because the errors cluster in predictable places. Mass 1 mg = 1000 mcg. 1 mcg = 0.001 mg. Volume 1 mL = 1000 µL (mcL). U-100 syringe: 100 units = 1 mL, so 1 unit = 0.0…
Extremely common question, phrased as though there's a correct number. There isn't — it's a choice with trade-offs. What adding more diluent gets you: a more dilute solution, so a…
This is the calculation everything else depends on, and it's worth writing out in full because the failure mode is a factor-of-ten error rather than a small one. Three quantities,…
