Näytteenottoputki

Näytteenottoputki refers to a sample collection tube used in medical and laboratory settings. These tubes are specifically designed for the safe and efficient collection, storage, and transport of biological specimens, such as blood, urine, or other bodily fluids. The primary purpose of a näytteenottoputki is to maintain the integrity of the sample until it can be analyzed.

Different types of näytteenottoputki exist, each tailored to the specific type of sample and the intended analysis. These variations often include different anticoagulants, preservatives, or additives within the tube. For example, blood collection tubes may contain heparin to prevent clotting or EDTA to chelate calcium ions, which are essential for coagulation. Other tubes might have a clot activator to speed up the clotting process or a preservative to stabilize the sample's composition.

The design of a näytteenottoputki typically includes a stopper or cap to prevent leakage and contamination. Many modern sample collection tubes utilize a vacuum system, also known as a Vacutainer system. This vacuum inside the tube helps to draw the correct volume of blood directly from the patient's vein, simplifying the phlebotomy procedure and reducing the risk of errors. The color of the stopper often indicates the type of additive present in the tube, providing a visual cue for laboratory personnel. Proper labeling of the näytteenottoputki with patient information and the date and time of collection is crucial for accurate identification and traceability.
