Capillary blood collection tube IVD, lithium heparin

Capillary blood collection tubes with lithium heparin are single-use devices designed to safely gather and preserve small blood samples from capillaries, often used for tests like microhaematocrit or neonatal bilirubin screening. Their sealed design prevents leakage and contamination during transport, ensuring reliable lab analysis.

These tubes are typically classified as in vitro diagnostics (IVDs) and may require compliance with standards like ISO 15189 or regional regulations such as the EU IVDR or FDA’s 21 CFR Part 809. They’re sold as sterile or non-sterile products, depending on the manufacturer’s intended use case, and are widely distributed through medical supply chains.
