How accurate are hemoglobin tests? With an accuracy of ± 2 g/dL 95% of the time (2 SD) and with a threshold for treatment for anemia at 9.5 to 11 g/dL, SpHb could be used to safety screen between 73 and 95% of the population to rule out anemia (SpHb values of ≥11.5–13 g/dL) and an additional 0.5% of the population to rule in anemia (SpHb values of…
