Lithium Heparin Blood Collection Tubes (100-Count)

Lithium heparin tubes are the correct collection tube for in-house canine progesterone testing, and this 100-count case keeps you stocked all season. Heparin plasma gives faster spin-down and reliable results on analyzers like Wondfo, Finecare, and VetChroma, with no waiting for a clot to form as you would with serum tubes. Each tube is pre-coated for clean, accurate plasma separation. For breeders running frequent progesterone panels across multiple females, buying in bulk saves money and prevents the frustration of running out mid-cycle. Pair these with our blood draw kit and micro centrifuge for a complete in-house testing station that puts breeding timing back in your hands.
