IN response to Alan Burridge’s letter regarding blood testing expenditure, I am surprised that their INR test results are not available there and then, avoiding the necessity to have it posted to them.

As a fellow Warfarin user, I go to my GP surgery for my INR blood test as required, usually every three/four weeks.

The practice nurse takes a minute finger pin prick sample which is put on a test strip, placed in a small portable device, which gives the INR reading in two/three minutes.

This is then recorded in my yellow book, together with any change in dose if required and the date of my next appointment.

The whole procedure takes less than 10 minutes, with little inconvenience to me!

Even allowing for the cost of the device (which can be purchased for £300/400 on a D I Y system, GP approval) this seems to me to be a more cost effective way of managing this procedure.
