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 or NPHL Test Request Form (completed in 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.
