How unaccurate is API KH test kit?

This weekend I did a test with the API KH and got 7dkh, then did the test with salferit and got 10 dkh which is closer to what I was expecting...

I usually find them to be pretty reliable if use a syringe to draw the 5ml of test water and ignore the line on the test tube. However, in a tank I have just finished cycling, my API Nitrate kit reads in between the 40 and 160ppm mark while ny Red Sea Pro kit reads 32ppm. Thats a big discrepancy to say the least and the first time Ive seen such.
