Game changer for FineCare Vet machine

Without this the serum would gel and be impossible to accurately pipette for progesterone tests. So, I tried it with this tube and got 20.08. Barely into the “ GO” zone. I didn’t feel sure about the result as my intact male wasn’t interested. But within hours he changed his tune and went bonkers. So I would guess it’s accurate ! I have no idea why they even suggest trying this machine without these tubes. A MUST for accuracy in my opinion.

Thank You Mary,
