Adverse effects during testing.

Nosebleeds
These can occur in a small number of cases but should be able to be resolved quickly by applying pressure to the area.
If the nosebleed lasts for over 15 minutes and if you begin feeling nauseous, you should contact a healthcare professional or NHS 111.
Allergic Reaction
The liquid within the extraction buffer should not make contact with the eyes, skin or be digested. However if there is accidental contact with the skin or eyes you must wash with a large amount of water. If there is irritation after this then you should contact a healthcare professional or NHS 111. 
If the solution is digested, contact a healthcare professional or NHS 111.
