How does a “Point of Care” drug test device/kit work?

Most “rapid detection Point of Care” drug test devices/kits utilise a technology called lateral flow. Sometimes called a “rapid test” which is based upon the principle of competitive inhibition binding. Therefore, drugs that may be present in the urine / oral fluid specimen compete against their respective drug conjugate for binding sites on their specific antibody. During testing a portion of the urine / oral fluid specimen migrates upward through a membrane strip by capillary action (also known as “wicking”). Based upon the presence or absence of a drug then a line will be visible or not in the “test” area (“T” line). The control line (“C” line) will be visible when the test strip has run correctly. All ITS “Point of Care” drug test devices/kits come with clear instructions for use and the support of a friendly and highly experienced team of industry professionals.
