NPHL has moved to an electronic ordering system, NUlirt, and it is now the preferred method to order all tests. Once ordered, print a "batch list" (see
NUlirt Guide).
Forms Required - NUlirt batch list of NPHL Test Request Form (completed in its entirety) must accompany the specimen to include the following information: symptoms and date of onset, pregnancy status, travel and vaccine history. Testing
will not be performed without all required information.
Please call NPHL Client Services at 402-559-2440 or toll free at 800-334-0459 for further clarification.
