just went online to check and see if this is the POC system we use, and it is.
now, at my work, we have short term patients, usually from 1 week to 3 weeks at most. so, we pull the records from the hospital and try to track the trends with dosing.
some people react so sensitive to the coumadin, and i don't feel safe with that either. however, we have also had severe discrepencies with our own lab. once, i had to send a pt out for INR of 8.6 (repeated twice by seperate sticks). went to hospital, pt came right back with their lab stating it was only 5.6 and they received some Vit K. i couldn't believe it!!
i don't see any issue of this FDA alert at work either. however, since the last nurse who opened the box didn't reorder, we are doing all the INR's by lab draws anyway. just as well to draw another tube if you're drawing a rainbow anyway
do you have a link to the FDA alert?? i know we've had this issue come up before with issues with certain lot numbers. docs always just made us draw instead.
sorry couldn't be more help, but wanted to say we've gone through it too.
