● Why should you wipe the first blood drop and not milk the finger when performing a capillary…

➤ How does milking the finger affect test results in capillary sampling?
Milking increases interstitial fluid mixing and hemolysis, which dilutes analytes like glucose, electrolytes, and bilirubin. It can also introduce skin contaminants and produce variable drop sizes. These factors lead to inaccurate or inconsistent laboratory values, often necessitating repeat sampling for reliable diagnostic information.
