Reportable Disease: | Positive results are reported to local or state health department within 7d. Refer to Nebraska DHHS Title 173, Communicable Diseases. |
Comments: | Pre-approval needed from state or local health department. Send approval to NPHL@unmc.edu or call (402) 559-9444. Once this test is performed, if: a) Negative - no further testing is done; b) Positive or equivocal - immunoblot testing will be performed on the original sample upon receiving a request. Sample will be held for 30 days only. Current CDC recommendations for the serologic diagnosis of Lyme disease are to screen with a polyvalent ELISA test and confirm equivocal and positive results with Immunoblot. Both IgM and IgG Immunoblots should be performed on specimens less than 4 wk after appearance of erythema migrans. Only IgG Immunoblot should be performed on specimens greater than 4 weeks after the disease onset. IgM Immunoblot in the chronic stage is not recommended and does not aid in the diagnosis of neuroborreliosis or chronic Lyme disease. Please submit requests for appropriate Immunoblot testing within 10 days. |
