Carry-over contamination rate mainly reflects the degree of contamination between samples. By measuring the high concentration sample 3 times (H1, H2, H3) and low concentration sample 3 times (L1, L2, L3), the carry-over contamination rate was calculated: carry-over contamination rate (%) = (L1 - L3)/(H3 - L3) ∗ 100%. When the carry-over contamination rate was not higher than 3%, the carry-over contamination rate would be accepted.
