Procedure
FILLING AND SEALING PT/INR (PROTHROMBIN TIME) CARTRIDGES USING DIRECT
FINGERSTICK SAMPLING
STEP ACTION
1. Remove cartridge from foil pouch and place the cartridge on a flat
surface.
2. Prepare lancet device and set aside until needed.
3. Clean and prepare the finger to be sampled using a 70% aqueous
solution of isopropanol (70% v/v). Allow the finger to dry
thoroughly before sampling. When disinfecting fingerstick skin
puncture sites, swabs or solutions containing substances other than
isopropanol (e.g. Chlorhexidine Gluconate) are not recommended.
Refer to the “Limitations of the i-STAT
PT/INR Test” section in the PT/INR
Cartridge and Test Information Sheet
for more information.
4. Prick the bottom side of the fingertip
with the lancet device.
5. Gently squeeze the finger, developing
a hanging drop of blood and perform
the test with the first sample of blood.
Avoid strong repetitive pressure (“milking”) as it may cause hemolysis or
tissue fluid contamination of the specimen.

Do not hold cartridge between the fingers
if using a syringe with needle to fill.
