Why Hemosense?
Why Hemosense?
Hi Gina (my first internet valve buddy), Why did I buy a Hemosense INRatio when I already have a Coaguchek? Good question. I buy a lot of techie stuff I really don't need. One of my activities is to help friends and people referred from my cardiologist and surgeon who need some reassurance with their testing technique and use of their monitors. A recent case involved a young man about 6 years post aortic valve who began to get badly conflicting results between his Coaguchek and the central lab He called and wanted to test side by side with my Coaguchek. I had been thinking about my 7 year old Coaguchek and wondering how accurate it was. I decided it was time to try the new Hemosense. My friend came over last Saturday after getting a lab vein stick and we began the tests. We each had 3 finger sticks before we were through.. I won't bore with the details but we think the central lab has a problem. The Coagucheks and the Hemosense were all pretty close. How close is close enough? I don't know. Thats the key question.
Today my INR with Hemosense was 3.2 with a PT of 31.7". My INR with Coaguchek was 2.7 with PT of 20"! I'd like to know, maybe Al could help, why the seconds vary so and give their respective INR's.
It must be due to the isi (sensitivity) of the thromboplastin but how?
The INR results were both in the therapeutic range. Are they close enough?
I like the INRatio. It is compact and user friendly. I intend to test side by side for the next few weeks. I'll let you know the results. Warm regards.
