Skin puncture blood most closely resembles venous blood, which is the blood collected from veins for laboratory tests. However, it may contain some interstitial fluid due to the puncture of capillaries in the skin during the collection process.
The laboratory report form should indicate that a specimen was collected by skin puncture to ensure accurate interpretation of results, as this method can influence the concentrations of certain analytes due to factors like hemolysis or contamination. It also helps laboratory personnel assess the validity of the sample and consider any potential discrepancies in results. Additionally, knowing the collection method aids in proper patient management and follow-up by healthcare providers.
EDTA specimens are obtained first to prevent contamination of the blood with elements released during the skin puncture process, such as potassium and glucose, which could affect the accuracy of subsequent tests. EDTA also helps to preserve the integrity of the blood cells for hematologic testing.
No special preparation is required other than cleaning and disinfecting the skin at the puncture site. Blood is collected in a tube by venipuncture.
It typically takes about 14 psi (pounds per square inch) to puncture human skin. However, the exact amount can vary depending on factors such as the thickness of the skin, the angle of the object, and the force behind the puncture.
No, a tattoo needle doesn't penetrate the skin deeply enough to puncture a vein.
Clean the skin if practical and necessary. Then, applicaiton of disinfectant if the skin is not punctured (alcohol) or antiseptic if the skin is punctured (betadyne, hydrogen peroxide). With puncture wounds, plan on a tetanus update, if necessary.
