+4 88, +5 97
I had a problem with the +4 test - went through 6 strips with the error message strip problem, try another.
I started freaking out, thinking he was too low - but the error message was not a too low warning, and I got the same error message on human blood.
Found another One Touch meter - an Ultra Mini - takes the same strips and batteries as the Ultra - and got this reading of 88.
Retested at +5 with original meter after successful test on myself.
This meter gave me reading of 97 - the 88 on the other meter may not be comparable to this meter.
Regardless, he is hungry, eating freeze dried chicken now, seems good.
I think the 97 is a good reading.
