Parasite Examination, Macroscopic
Also known as: ECTO ID
Use
The Parasite Examination, Macroscopic test is essential for the detection and identification of macroscopic parasites. This includes the examination of larvae, worms, arthropods, insects, and ticks. It supports clinical decision-making by providing timely identification of ecto parasites or larval forms, which could be relevant in diagnosing parasitic infections and guiding appropriate treatment regimens.
Special Instructions
Patient preparation involves collecting a macroscopic parasite or scraping the skin if scabies is suspected. Specimen should be immersed in 5-10 mL of 70-80% ethanol or other alcohol in a clean container. Specimens should not be stool, unpreserved, or preserved in non-alcohol mediums. The specimen source is preferred for accurate testing.
Limitations
This test is limited to the identification of macroscopic parasites and cannot identify non-macroscopic or microscopic organisms. Specimens not preserved correctly, or those that are stool or unpreserved, may be rejected. Identification is based on visual and microscopic examination, which may not detect all parasites if they are degraded or improperly preserved.
