While both serum creatinine, cystatin C, eGFRs, and mGFRs (by creatinine, inulin, iothalamate) all have relatively large and proportionately similar reference ranges [8,9], the within-individual variations for serum creatinine, cystatin C, and eGFR are much lower than for mGFR by creatinine clearance [5,10], or by iothalamate and inulin methods [7,11]
IM injections are often recommended for individuals with more severe B12 deficiencies who require rapid replenishment
