1 min read

What takes place through a PT/INR examination?

The examination may perhaps be accomplished on a blood sample from a vein or a fingertip.

For a blood sample from a vein:

A well being care professional will choose a blood sample from a vein in your arm, using a little needle. Soon after the needle is inserted, a little quantity of blood will be gathered into a examination tube or vial. You may perhaps really feel a minor sting when the needle goes in or out. This normally requires much less than 5 minutes.

For a blood sample from a fingertip:

A fingertip examination may perhaps be accomplished in a provider’s workplace or in your property. If you are having warfarin, your provider may perhaps recommend you examination your blood frequently using an at-property PT/INR examination kit. Throughout this examination, you or your provider will:

  • Use a little needle to puncture your fingertip
  • Accumulate a drop of blood and position it onto a examination strip or other particular instrument
  • Position the instrument or examination strip into a product that calculates the benefits. At-property products are little and lightweight.

If you are using an at-property examination kit, you will have to have to review your benefits with your provider. Your provider will permit you know how he or she would like to obtain the benefits.
