Why are my tests negative?

Many chronic urinary tract infection (UTI) sufferers have had their symptoms dismissed by their GP or urologist on the basis of dipstick tests and mid-stream urine (MSU) cultures. Worryingly, these tests are seriously flawed.

  • Standard mid-stream urine (MSU) cultures miss 90% of chronic urinary tract infections
  • Dipstick analysis (leucocyte esterase test) miss at least 60% of chronic urinary tract infections.

Just because your tests don’t find evidence of an infection, this is not evidence that you don’t have a UTI.  Full details about this are on our Urine Testing page.
