Standard curve
Tg reference calibrators of 10 ng/mL, 50 ng/mL, 100 ng/mL, 200 ng/mL,
and 300 ng/mL were added to Tg-POCT test paper as a drop of 60 µL. After
reaction at 30℃ for 5 min, the test was performed. The T/C value, which
was the signal value, was measured five times and CV was counted.
According to the statistical method, T/C ratio of the detected sample
was taken as the ordinate, and the concentration of Tg standard was
taken as the X-coordinate. The equation was established, and the
standard curve was synthesized. Linear regression coefficient was 0.976.
The high value was partly due to the hook effect. Overall, the curve was
linear and smooth.( Table1. standard curve Figure10. standard curve)
