Help, please, research project on phenolphthalein poisoning. Need info on
false positive and false negative drug and food interactions on screening
test of phenolphthalein with sodium hydroxide. I have done extensive
searches on Medline,MELVYL at UCSF,GLADIS at UCB, LOIS at
LANE(Stanford),and NML. I have the test procedure but not any info
regarding known drugs or foods such as anthocyanin(fruits) that cause false
positive or false negative test results. I am involved in a personal
situation and any info or help would be greatly appreciated. I have a
medical and chemical educational background and am not looking to tread on
any one's research projects. I need the information strictly for personal
use. Thank you again ahead of time.

 Thank you
