Anemia can affect the accuracy of glucose readings given by a glucometer. Mann et al developed equations for correcting readings from 4 different glucometers for various hematocrits. The authors are from Fort Sam Houston in Texas.
Parameters:
(1) glucometer type
(2) glucometer reading
(3) hematocrit as a whole number

corrected value for Accu-Chek Advantage G3
= (0.8248 * (glucometer reading in mg/dL)) + (3.3895 * LN(hematocrit)) - 7.6008
corrected value for Accu-Chek Inform G2
= (0.8368 * (glucometer reading in mg/dL)) + (1.959 * LN(hematocrit)) - 3.621
corrected value for Precision PCx G4
= (0.1866 * (glucose reading in mg/dL) * LN(3.729 * (hematocrit))) - 2.8203
corrected value for SureStep Flex G1
= (0.2104 * (glucose reading in mg/dL) * LN(3.3249 * (hematocrit))) - 11.3934
