  • potassium test

    hi- I am not yet diagnosed, and have only had symptoms for about 2.5 weeks, but I might be able to get a hydro scheduled for next week. Since it isn't always conclusive though, has any ever just had the potassium test, and what is involved in that test?

      I had the potassium leak test several years ago, performed by a nurse who has co-authored medical papers on it ("Potassium leak test predicts outcome in interstitial cystitis." Teichman JM, Nielsen-Omeis BJ. J Urol 161:1791, 1999. "BJ" is "Betsy"). If you're sensitive to it, it's more painful than simply putting in saline solution; and they simply have you tell them what you feel. (It took me a year after having symptoms to even agree to have it; had cystoscopy, MRI, and nerve blocks before that).

      In a review, Vicki Ratner, M.D., of the Interstitial Cystitis Association, noted, "Although the potassium chloride sensitivity test has gained in popularity, this test cannot be considered a reliable, definitive test for IC" (Urology 57 [Suppl 6A], pp. 89-94, June 2001). I had my potassium test done since I was already having urodynamics anyway (and the catheter was already in). It was negative. But there's about a 40% false negative rate according to some studies.

      In a study done by Dr. Parsons (Journal of Urology 159, pp. 1862-6, June 1998, "The role of urinary potassium in the pathogenesis and diagnosis of interstitial cystitis"), he found that potassium sensitivity is also present in acute urinary tract infections.

      Sorry if I've overloaded you with too much information and all these specifics (it's the scientist in me). Two and a half weeks seems too soon to have anything invasive done like hydro or potassium test, but that's just my opinion. Anyone else?

        I had the potassium sensitivity test done after having a hydrodistention that did not show the "classic" signs of IC. I had a positive reaction to the potassium. I found it much less traumatic than the hydro. Basically what they do is first instill sterile water. They will ask you to rate any sensations you are having on a scale that will be given to you. Then they drain the water and next instill the potassium solution, again asking you to rate your sensation on that same scale. Then the solution is drained out. They should then rinse you out with sterile water and instill a lidocaine solution to ease any post-test discomfort.

        I did not flare really from the test. I felt about the same afterwards as I did beforehand. It was nice to have the several hours of relief, though, from the lidocaine.

        I hope this helps to answer any questions you have.
        Good luck!
