Variability of ferritin measurements in chronic kidney disease; implications for iron management

2nd, they assume ferritin is reliable. It is horrible! Large differences between assays, significant day-to-day intra-assay variability, and poor short and intermediate term intra-patient variability. https://t.co/usJXsIkvyG

RT @DrDanMO: @hswapnil @DavidCWheeler2 There was no central lab in PIVOTAL, ergo there is no single ferritin value. Another reason there is…
