Gastric intrinsic factor (GIF)
Links to databases
Gastric intrinsic factor is a secreted glycoprotein produced by the parietal cells of the stomach. It is necessary for the absorption of vitamin B12 in the small intestine. Defficiencies in gastric intrinsic factor lead to malabsorption of vitamin B12 and subsequent megaloblastic anemia.
Analytical Measuring Range
Calibrator curve for validation data (generated in multiplex)
- Within run precision Coefficient of Variation (CV)
- Between run precision Coefficient of Variation (CV)
Precision (repeatability) is calculated from linearized NPX values over LOD.
