K2 and K3 EDTA blood collection tubes are essential components in clinical diagnostics, designed for accurate results across various healthcare applications. These tubes differ by anatomical sampling site and intended test, making correct selection and usage critical to ensure reliable outcomes.
Primarily used in hematology and cross-matching tests, these tubes are also suitable for gynecological applications, including cervical sampling and smear testing. Their composition ensures secure handling of samples for both routine and specialized analysis.

How to Identify EDTA Tubes
Blood collection tubes are differentiated based on the type of test they are intended for. Key identifiers include cap color, presence of vacuum, and gel content. EDTA tubes, especially used for hematology and high-precision blood testing, are easily recognized by their purple caps.
