What is the first step when performing a fingerstick for blood glucose testing?

The first step when performing a fingerstick for blood glucose testing is to clean the area with an alcohol swab and allow it to dry. This practice is crucial in preventing infection and ensuring that the sample is not contaminated, which could affect the accuracy of the test results. Cleaning the site reduces the presence of bacteria, debris, or other substances that might interfere with the glucose measurement.

Allowing the alcohol to dry is also important, as using a wet swab can cause a stinging sensation and may alter the blood sample due to residual alcohol. Proper cleansing techniques are an essential part of maintaining hygiene standards and ensuring patient safety during the procedure. This preparatory step is foundational before moving on to the actual collection of the blood sample.
