ABC of Safety in the Biological Sciences
FINE NEEDLE BIOPSY
The dangers inherent in the technique of
fine needle biopsy are due to the following:
- Needle prick, especially in cases of
contagious disease. It is important to be aware of the relevant
medical history before attempting to obtain material for
examination. If a needle prick does occur seek immediate medical
advice.
- Aspirated material entering an open
wound on the hand. Dress any open wounds and wear gloves before
aspirating any lesion.
- Most aspirates are fixed in methanol
and stained with Giemsa. Methanol is highly toxic and Giemsa is
potentially carcinogenic. The dye solution is also toxic and
inflammable.
