The Parasitic Diseases Branch contains a laboratory unit dedicated to reference diagnosis on difficult cases of parasitic infections. This unit serves as a final reference laboratory for state public health departments as well as for laboratories in the private sector. It is also dedicated to developmental diagnostics and pathogen discovery. Our reference diagnostic services include telediagnosis, morphology, serology, and, when necessary, molecular testing.

When a laboratory would like assistance in identifying a parasitic organism, or confirmation of a presumed diagnosis, and they have access to a digital camera, they can use telediagnosis. Telediagnosis involves email transmission of data, such as digital images captured from samples and clinical and travel history, to CDC. Response to these inquiries can be provided in a matter of minutes to hours. If you are a laboratorian or a pathologist and want to use telediagnosis assistance*, please visit the Diagnostic Assistance section on the DPDx Web site.

*Telediagnosis assistance is free and is available Monday-Friday during regular business hours only. If you have an urgent case, please do not delay case management.

Many cases of parasitic infection can be identified through ova and parasite testing or examination of blood smears. Our reference diagnostic laboratory performs morphologic examinations for identification of parasites associated with human infections.

Selected serological testing for diagnosis of parasitic diseases is available through our serology laboratory. See our list of available tests.

Selected PCR-based tests are available in our reference diagnostic laboratory for identification of certain parasites at the species level for cases in which morphologic examinations are not conclusive for identifying parasites and further molecular analysis, e.g., DNA sequencing analysis, is necessary. Our diagnostic laboratories offer DNA-based testing on a variety of clinical specimens, including stool, blood, tissue and exudates.

For more information about laboratory procedures for identification of parasites, please visit our DPDx: Laboratory Identification of Parasites of Public Health Concern Web site.


Given the “state of the art parasitic testing lab” the CDC has at it’s disposal I have to admit I’m pretty perplexed on a lot of things. I mean, in all honesty how hard would it have been to have taken 20, 30, 50, or 100 people suffering from Morgellons and just have them tested and rule out known parasites?

On this page on the CDC WebSite it says

May I send samples to the CDC laboratories for confirmation of this condition?

CDC is not able to accept specimens or samples for testing, and we are not aware of any public health labs that are performing tests specifically related to this condition. Persons who believe they may suffer from this condition should contact a licensed healthcare provider for evaluation and medical care.

So, either the CDC doesn’t know it has the aforementioned lab or the CDC knows this condition is not parasitical in nature. It just doesn’t add up. I mean, they can’t even accept specimens if they are taken by a doctor? Not even blood for one of the tests listed above? The statement above serves only to turn us away, without so much as using this lab which our tax money paid for?

I was alerted to this information via a thread on LymeBusters …

  1. well now,..Mundane,…Kinda makes one laugh a bit, far as I understood the C.D.C., supposed to have Doctor’s around the country that they can activate in case of a pandemic,…yet they say they have no Doctor’s,.lie,….and what your information is saying if I’m not wrong, a backup for Doctor’s round the country,…so seems to me that’s where the problem lies–or is it lays–oh well they still lie….lol,..good to see you hard at work,…Government stuff is always complicated. Go figure!! help explain if I’m wrong in my thinking,…cause ryte naw I am very confused.
