Rigiscan
RS
Description
"RigiScan" test helps evaluate erectile dysfunction by recording changes in penile rigidity and circumference during sleep. The device is worn overnight to track how well erections occur without conscious effort. Reduced firmness may indicate physical issues like poor blood flow, while normal readings suggest a psychological cause. This test is useful for men with persistent ED. Results help guide care plans that may include therapy, medication, or further testing to improve sexual function and overall health.

Key Reasons For Testing
Erectile Dysfunction Evaluation: Provides objective data on nocturnal penile tumescence, aiding in accurate diagnosis.
Differential Diagnosis: Distinguishes between organic and psychogenic erectile dysfunction, guiding treatment.
Assessment of Erectile Function: Quantifies penile rigidity and tumescence, characterizing the severity of dysfunction.
Treatment Monitoring: Tracks therapy effectiveness, helping adjust treatment plans over time.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
