Also, I believe it is a dip stick drug test, from what I remember when I had to take one to get the job. The stick has like 4-5 prongs, I am guessing for the different types of drugs. If this info helps let me know, if you guys have any idea of what type of test this is. If you do not think it will test for pH, I might try the bleach method....let me knwo, thanks.(Test is given at my work place, no labs)
