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.
