How intensive should the colour of the indication line of a SERATEC® pregnancy test be as to mean a positive result?
The intensity of the colour depends on the concentration of HCG in urine samples. According to how advanced pregnancy is, as well as on the individual rate of production and attenuation, the membrane may turn from slightly pink up to darkly red. Even the lightest observable coloured line in the region of indication shows the presence of HCG and means therefore a positive result.
