What transpires during a PT/INR exam?
The exam might be done on a blood sample from a vein or a fingertip.
For a blood sample from a vein:
A overall health care professional will acquire a blood sample from a vein in your arm, applying a smaller needle. After the needle is inserted, a smaller quantity of blood will be collected into a exam tube or vial. You might truly feel a small sting when the needle goes in or out. This normally usually takes significantly less than five minutes.
For a blood sample from a fingertip:
A fingertip exam might be done in a provider’s workplace or in your property. If you are getting warfarin, your supplier might advocate you exam your blood often applying an at-property PT/INR exam kit. In the course of this exam, you or your supplier will:
- Use a smaller needle to puncture your fingertip
- Collect a fall of blood and position it on to a exam strip or other unique instrument
- Position the instrument or exam strip into a device that calculates the final results. At-property gadgets are smaller and light-weight.
If you are applying an at-property exam kit, you will want to evaluate your final results with your supplier. Your supplier will let you know how he or she would like to get the final results.
