The Vet Field Kits Lithium Heparin (Green) Tubes provide a reliable solution for collecting blood samples in large animal veterinary practice, particularly where plasma-based biochemical analysis is required.

Lithium heparin prevents clot formation, allowing blood samples to be centrifuged immediately after collection. This makes green top tubes especially useful for time-sensitive testing and on-farm sample collection, where delays in clotting could compromise sample quality. They are routinely used to support assessment of metabolic and nutritional status, including investigations into energy balance, electrolyte disturbances and mineral deficiencies.

In herd health programmes, lithium heparin tubes are commonly used for monitoring liver and kidney function, investigating conditions linked to poor performance, reduced milk yield, dehydration or systemic illness. They are also suitable for selected hormone and stress-related measurements, forming part of wider health and welfare reviews and veterinary-led herd management plans.

These tubes are widely used across cattle, sheep and equine practice and play a supporting role in private and voluntary herd health schemes, where biochemical monitoring complements disease control and productivity-focused health planning.

As with all blood collection systems, correct tube selection is essential. Green top lithium heparin tubes are intended for plasma biochemistry and are not suitable for routine haematology or antibody-based disease testing, where alternative tube types are required.

Designed for practical field use, Vet Field Kits – Green Top Tubes support consistent, high-quality sample collection as part of a proactive, data-led approach to large animal health management.
