Thank you for posting your query. Apologies for the delay.
I am Dr.R.K and I pleased to assist you.
The values you have posted is the reference value of the test. ( It means if the test result is 0 it is negative, if it is 1 - boderline, 2 it is positive). So you wife might have got a result which is any one of the three.
Please include your wife's test result. It should be either 0, 1 or 2.
