Scabies Examination
Use
Detection of the itch mite that causes scabies in humans
Special Instructions
Place a drop of mineral oil on a sterile scalpel blade for collection. Scrape a newly-developed papule vigorously six or seven times to remove the top. Transfer scraped material mixed with oil to a glass slide, place a second slide over it, and secure with a rubber band. Adequate collection is crucial for accurate test results.
Limitations
The effectiveness of the test may be compromised if specimen collection is not performed adequately. False negatives can occur if mites are not captured in the skin scraping or if specimens are mishandled. Mislabeling or inadequate specimen quantity may also result in test rejection. Additional confirmatory tests or repeated collections may be needed for suspected cases when initial results are negative.
