Goldenrod Lancets come in several point lengths for various size animals and blood volumes required. Choose The Proper Lancet Point Length Corresponding To The Age Of The Mouse And The Volume Of Blood Needed.

Point Lengths

For Mice:

3mm - for only 1 or 2 drops
4mm - under 2 months
5mm - 2 to 6 months
5.5mm - over 6 months

For Rats:

5.5mm - 6 mm Under 3 months
6mm or 7mm  - 3 to 4 months
7mm or 8mm - over 5 months

Unanesthetized rats can be manually restrained for access to the saphenous vessel.
One rear leg is isolated and a scalpel blade used to bluntly remove hair over the vessel. A small amount of Puralube® ointment is applied topically prior to pricking the vein with the MEDIpoint’s lancet. The Puralube ointment allows the blood drop to remain localized and away from the skin and hair on the leg. Approximately 4 - 5 drops of whole blood (~100 µl) can then be directly collected into a collection tube, prior to sample analysis. Blood flow can be stopped at any time by applying a compress to the site for a few moments.

For Saphenous Bleed use a 3mm or 4mm point length.
