Hi, We had few cases where the mother was positive and the new born negative for drugs of abuse. Actually we are doing DOA on the urine of new born. It seems that the meconium is a better specimen than urine. I will appreciate to hear from colleagues who have bad or good experience with DOA on meconium.
