e-Laboratory Results

The time it takes for test results to be available depends on various factors, such as the type of test, method used, and where the particular test was performed. Rapid tests performed at home or in a clinic can give results within minutes. Tests that are performed at local labs or commercial reference labs may take a few hours or up to several days after the sample is received at the lab.

Typically, a blood sample is taken by inserting a needle into a vein, usually in your arm. Before your blood is drawn, an elastic band is tied around your upper arm to increase blood in the veins, and the puncture location is wiped clean with an antiseptic. A blood draw using a needle may cause a temporary sting. The blood draw normally lasts for less than a minute. Sometimes a blood sample is collected by puncturing the tip of a finger and drop(s) of blood are collected onto a test pad or filter paper, or into a small tube.
