A member asked:

Nasal liquid tested for csf 2 times. had 1/2 teaspoon in tube, they said not enough- but also not detected. what now? keep testing?

A doctor has provided 1 answer

Different lab: If the lab told you that 1/2 a teaspoon was not sufficient, you need to use a different laboratory for testing.
