  1. aIn iodine test, Y and N indicate positive result with observable color change from brown to blue, and negative result without color change (i.e. brown), respectively
  2. bIn hCG detection, Y represents the presence of two pink bands at the Test (T) and Control (C) sections of pregnancy test strip, while N represents the presence of a single pink band at the C section only
  3. cAssay buffer was set as blank and the data represent mean ± standard deviation (n = 3)
  4. dIn diagnostic PCR, Y and N represent the presence and absence of amplified products, respectively
