drug site/drug position

English to Swedish Medical Medical: Instruments

"For each test, a fresh disposable cartridge and collection kit are used. The oral fluid (saliva) and buffer solution rehydrate gold-labelled antidrug antibodies contained within the cartridge. This mixture travels by capillary action across an array of immobilized drug sites. The countdown timer allows this chromatographic development of the cartridge. Colour development at an immobilized drug position is dependant upon drug concentration."
