Which test?

#1
Hi

I have a test that uses two reagents.
The two reagents each have a batch number and they can be used in differing combinations.
The test is then applied to a sample and the result is either positive or negative.

This is my dataset:

What statistical test should be applied to find out if the range of differing 'test positive rates' are within the expected range or are a function of the differing comination of batches of reagent used in each test?

Thanks

James
