laskimoverinäytteestä

Laskimoverinäyte, also known as venous blood sample, is a common laboratory procedure used to collect blood from a vein. This is typically done to analyze various components of the blood for diagnostic and monitoring purposes. The most common site for venipuncture is the antecubital fossa, located in the bend of the elbow, due to the prominence and accessibility of the veins there.

The procedure begins with preparing the venipuncture site, usually by cleaning it with an antiseptic. A tourniquet is then applied above the chosen vein to engorge it with blood, making it easier to locate and access. A needle attached to a collection tube is inserted into the vein, and the required amount of blood is drawn into the tube. Once the collection is complete, the needle is removed, and pressure is applied to the site to stop any bleeding.

Laskimoverinäyte can be used to measure a wide range of substances, including blood cell counts, electrolytes, glucose levels, cholesterol, liver and kidney function markers, and specific proteins or antibodies. The collected blood is then transported to a laboratory for analysis. The results provide valuable information to healthcare professionals for diagnosing illnesses, assessing treatment effectiveness, and monitoring a patient's overall health. Proper technique and sterile equipment are crucial to ensure accurate results and prevent complications such as infection or bruising.
