After a few months of rapamycin 6mg/1-week, my numbers on a blood test 08/08/25 by LabCorp. My ferritin was flagged as “LOW” by LabCorp:
Iron Bind.Cap.(TIBC) - 405 ug/dL (ref. 250 - 450)
UIBC - 330 ug/dL (ref. 111 - 343)
Iron - 75 ug/dL (ref. 38 - 169)
Iron Saturation - 19 % (ref. 15 - 55)
Ferritin - 20 ng/mL LOW (ref. 30 - 400)
RBC - 5.2 x10E6/uL (ref. 4.14 - 5.8)
Hemoglobin - 15.4 g/dL (ref. 13 - 17.7)
Hematocrit - 48.2 % (ref. 37.5 - 51)
MCV - 93 fL (ref. 79 - 97)
About three months before I took rapamycin on a test at UCLA, 10/23/24 my numbers were:
Ferritin - 39 ng/mL (ref. 8 - 350)
Iron - 127 mcg/dL (ref. 41 - 179)
Iron Binding Capacity - 354 mcg/dL (ref. 262 - 502)
Saturation - 36 %
RBC - 4.86 (ref. 4.41 - 5.95 x10E6/uL)
Hemoglobin - 15.1 g/dL (ref. 13.5 - 17.1)
Hematocrit - 45.2 % (ref. 38.5 - 52)
MCV - 93 fL (ref. 79.3 - 98.6)
Note the different reference intervals between these two labs. Ferritin was within normal range on this reading, and at 39 would have been within range of LabCorp - but the LabCorp reading of 20 would’ve been within range according to the UCLA lab, while being flagged as “LOW” by LabCorp. Either way, FWIW both iron and ferritin dropped substantially in the second reading (after rapamycin).
