Flow meter urine testing: a practical proposition in patients attending for urodynamics?
Testing urine by dipstick in the sample from the flowmeter is a feasible option, thus saving the patient an inappropriate catheterization, with the risk of bacteraemia during urodynamics, and allowing the flowrate to be measured.
For CSF specimens that cannot be immediately processed, the addition of RPMI appears to significantly improve cellularity at 24 hours to 48 hours after their receipt in the laboratory.
