Does Advial Or Benadryl Affect Blood Test Report?

I just had my blood works done and everything came back perfect in range with exception of only the- rbc nucleated auto count which came back at 0.2. I am told with everything else in line that i have nothing to worry about. I did take Advial last night as well, I took banadryl. Not sure if this can change the reading.

Hi
Thanks for posting your query on HCM.
I appreciate your concern for blood tests
Assuming that you are being tested for drugs of abuse, the use of Benadryl may give a "FALSE POSITIVE" reaction for the drugs like Opioids, Phencyclidine and Tricyclic antidepressants.
Where as Avial may give a false positive reaction for drugs like barbiturates, Methadone, and Phencyclidine.

So, in view of the above explanations the above mentioned drugs in your query may interfere with the readings of the commonly abused drugs as listed.

Hope this answers your query.
