Question: 1 / 400

Which test cannot be performed using a fingerstick procedure?

Glucose test

Blood cultures

The blood culture test cannot be performed using a fingerstick procedure because it requires a sterile collection environment to avoid contamination and accurately diagnose infections. Blood cultures are used to detect the presence of microorganisms in the blood, which necessitates drawing blood using a more traditional venipuncture method to ensure that the sample is uncontaminated by skin flora.

In contrast, tests such as glucose, hemoglobin, and cholesterol can be conducted using fingerstick samples as they do not require the same level of sterility and can derive adequate information from small blood volumes. These tests are commonly performed in point-of-care settings due to their convenience and the ability to obtain quick results with minimal patient discomfort.
