Final answer:
Cystoscopy and potassium sensitivity test are not recommended for diagnosing Interstitial Cystitis due to their invasiveness and potential to worsen symptoms. Urinalysis and urine culture, on the other hand, are important in ruling out infections and are typically part of the initial evaluation process.
Step-by-step explanation:
The two tests that are NOT recommended for Interstitial Cystitis are cystoscopy and potassium sensitivity test. Both tests can be invasive and may exacerbate symptoms in individuals with Interstitial Cystitis. It is important to note that urinalysis and urine culture are commonly used to rule out urinary tract infections by detecting bacteria, such as Escherichia coli or Klebsiella pneumoniae, and inflammatory cells, which are not typically present in Interstitial Cystitis. A urine culture is especially important to conduct after a positive urinalysis to confirm a bladder infection. Conversely, tests like urodynamic testing and bladder biopsy may sometimes be used to evaluate bladder function and check for bladder cancer or other pathological conditions, but they are not routinely recommended in the initial diagnosis of Interstitial Cystitis.
