Spot/ random urine in leak proof container. This test is prone to adulteration (dilution, swapping of samples etc.) by clients undergoing testing. Referring institutions should ensure that there is proper chain of custody. The lab reserves the right to take safeguards against adulteration e.g., requesting sample recollection, supervised collection etc.

Differentiate between osmotic vs. non-osmotic diarrhea.

CSF in sterile, leak proof container. Test components: CSF cell count, CSF biochemistry (glucose and proteins), Gram stain and ZN stain.

SAMPLE TYPE: If multiple CSF tests are required, minimum is 5ml divided between 3-4 sequentially labelled tubes. When this is done, tube 1 is used for chemical tests.
