Inaccurate Hemoglobin- not FDA approved - 3 dollar for each full test – Ember by Cercacor Review

I checked my hemoglobin using an blood machine in lab and it was 16.7 g/dl but at same time the ember showing my Hgb is 14.1 . Now I understand why FDA did not approved the device ? also each time I do a full test it costing me 3 dollars and I have to pay through buying new credit package which start at $25 which can be used for 8 full test
