Question and options
For the analysis of foetal drug exposure, which of the following matrices is preferred?
- Meconium
- Blood
- Vomit
- Colostrum
Answer and explanation
Correct answer: A - Meconium
Meconium accumulates drugs from about the 12th week of gestation, giving a long window for detecting foetal drug exposure. Blood reflects only recent exposure, and vomit and colostrum do not record what reached the foetus during pregnancy.
