The Parasitology Laboratory identifies various types of blood-borne, intestinal and skin parasites via microscopic analysis and/or molecular detection.
Microscopic Identification: Parasites in stool, tissue or other body fluid
Molecular Detection Tests (CLEP Certified) and Preferred Sample Type:
- Babesia microti: whole blood
- Blastocystis hominis*: stool (unpreserved or in ethanol-based preservative)
- Cryptosporidium hominis/parvum*: stool (unpreserved or in ethanol-based preservative)
- Cyclospora cayetanensis*: stool (unpreserved or in ethanol-based preservative)
- Entamoeba coli*: stool (unpreserved or in ethanol-based preservative)
- Entamoeba dispar*: stool (unpreserved or in ethanol-based preservative)
- Entamoeba hartmanni*: stool (unpreserved or in ethanol-based preservative)
- Entamoeba histolytica*: stool (unpreserved or in ethanol-based preservative)
- Giardia duodenalis*: stool (unpreserved or in ethanol-based preservative)
- Leishmania species: whole blood
- Plasmodium falciparum, P. vivax, P. ovale, P. malariae: whole blood
- Plasmodium falciparum NGS for drug resistance: whole blood
- Trypanosoma brucei: whole blood
- Trypanosoma cruzi: whole blood
*Molecular detection is performed on samples with a negative microscopy result, or if specifically requested.
Culture Detection: Leishmania
- Cryptosporidium species: stool
- Entamoeba histolytica/dispar: urine, liver aspirate, whole blood
- Free Living Amoeba: misc.
- Leishmania: skin punch/skin scrape (see below for instructions)
- Microsporidia species: stool, urine, corneal scrape
- Various Helminths: misc.
Note: This is not a complete list of all organisms accepted. More information can be found in the test catalog in the Remote Order application. If you would like to submit a sample but are not sure if the laboratory tests for it, please contact the Parasitology Laboratory by phone at (518) 474-4177.
CDC Sample Submission: Requests for parasitology testing at the Center for Disease Control and Prevention are submitted through the NYSDOH Parasitology Laboratory.

Specimen Collection and Submission Guidelines
The Parasitology Laboratory accepts many different samples for analysis. Please see the information below regarding preferred sample collection and submission criteria as well as sample shipping instructions and guidelines. If you have specific questions about collection/submission not addressed below, please contact the Parasitology Laboratory by phone (518) 474-4177.
Who can submit a specimen? All specimens must be submitted by a NYS CLEP-permitted laboratory or a licensed physician.
The Wadsworth Center is a reference laboratory. Use local or commercial laboratory services whenever available.
Supplies: Call the Order Desk at (518) 474-4175 to order parasitology kits to be tested at the Wadsworth Center. An Infectious Diseases Requisition (IDR) Form must be included for each sample. A Non-permitted Laboratory Test Form must be completed for each specialized molecular detection test.
- Stool: preferably submitted in ethanol based fixative such as Total-Fix® or EcoFix® or unpreserved (kept frozen)
- Blood: EDTA preserved
- Live/dead specimen (such as fly, larvae, or worm): fixed in ethanol
- Leishmaniasis: Biopsy of lesion and/or needle aspirate (Specimen Collection Instructions for Leishmaniasis)
- Scabies: Skin scraping instructions
- Cerebral Spinal Fluid (CSF): in labeled vial, on ice or cold pack
Required Specimen Submission Information
If you have access to the Health Commerce System (HCS) and the Clinical Laboratory Information Management System (CLIMS), follow steps below:
- Log onto the Health Commerce System (HCS)
- Select 'CLIMS'
- Under the desired heading, select 'Remote Order'
- Click on the tab that indicates the type of sample you would like to submit: human, animal, environmental, etc.
- Fill in the screens, ‘Place the Order’, print form and submit with specimen.
This method provides many advantages over paper submission including specimen tracking, notification when results become available, online access to results and access to testing catalog. Should you encounter difficulty, please access the Reference Guide in the Remote Order application or contact our outreach support team.
Note: If you are from a licensed clinical laboratory with a valid PFI number or county or regional health department your HIN/HCS coordinator can grant you access to CLIMS (and create your HCS account if needed). For all other access, the Request for Access to the Wadsworth Center Laboratory Information Management System (CLIMS) form must be completed, signed and faxed to (518) 474-8140 or (518) 473-1326.
If you do not have access to HCS/CLIMS, complete the Infectious Diseases Requisition form, print and send with the specimen.
For each non-CLEP certified test, complete a Non-permitted Laboratory Test Form.
