A carryover in chemistry analyzer means a disturbance in readings because:
a. The analyzer was carried and placed at a different place.
b. The previously measured solution was still in the cuvette
c. The current solution is overflowing in the cuvette.
(b) Carryover is due to contamination by a previous sample. It is calculated by measuring a high standard and a low standard each 3 times then applying the following formula:
Carry over = (contaminated low – actual low) / contaminated high – actual high).
