Please help me understand. iron 113 range (37-170) tibc 426 (265-497) iron sat 26% (15-50) ferritin is low 5.5 (6.2-137) vitamin b12 is 241 (239-931)?

Follow it: Reference ranges are set so that a few percent of healthies fall outside on either side. Your serum ferritin is low-ish. Labs mean nothing apart from history and physical exam; if you're anemic, consider mixed iron deficiency and chronic inflammation if it fits and seek others causes (retic count). Check stool and urine to be sure you're not losing blood; discuss your diet & monthly loss.
