VARIANTnbs Sickle Cell Program

VARIANTnbs Sickle Cell Program is a reference HPLC method with high resolution hemoglobin variant screening (HbS, HbC, HbD, HbE), that also provides reports with presumptive pattern identification.

Unlike other newborn screening programs, the use of FADC/FAES retention time markers increases confidence in our HPLC system's ability to reveal hemoglobin variants.
