My wife was in our upstairs bathroom for appx ten mins. I had put bleach in a clogged toilet that I was having trouble plunging earlier in the day. She ended up in the ER frpm a seizure later that day. She never had one before. They did a blood ttest and said she had very low potassium. Also that there was PCP in her system. We don't use illicit drugs.????

Steve,

Breathing in the fumes from trying to clear a plugged toilet would not cause her blood tests for potassium.

It sounds like your wife had a blood test for drugs, not a urine test. In blood tests things are more accurate, however, false positives can occur. While I do not believe that breathing in the urine/chlorine fumes would lead to a false positive PCP blood test I can tell you that any positive tests found on routine drug screenings are confirmed by MS/HPLC testing.

These follow-up tests are very, very accurate and would confirm that the first PCP test result was false.

So. What is the take home message? You shouldn't worry about this blood test result. It will not be held against your wife without confirmation by the above, sensitive and specific, re-testing.

Dose this make sense to you?
