OL-15C Footnotes
- Isolate/specimen submission to the State Public Health Laboratory required. See isolate/submission supplemental guidance by pathogen.
- Only laboratories with electronic file reporting are required to report positive results.
- Specify species/serogroup/serotype.
- Sterile site: sterile uids (blood, CSF, pericardial, pleural, peritoneal, joint, or vitreous), bone, internal body site (lymphnode, brain, heart, liver, spleen, kidney, pancreas, or ovary), or other normally sterile site including muscle. For CRE, CRAB, and CRPA also include urine or sputum; for CRAB and CRPA, also include wounds.
- Report all C. difficile positive stool samples by electronic reporting or upon request from DPH.
- Report peak ALT and Total Bilirubin results if conducted within one week of HAV positive test, if available. Otherwise, check “Not Done.”
- Negative HBsAg and all anti-HBs results only reportable in children ≤ 2 years old.
- Report positive antibody, and all RNA and genotype results.
- Report all HIV antibody, antigen, viral load, and qualitative NAAT results. Negative HIV 1/2 Ab/Ag, HIV genotype (DNA sequence) and all CD4 results are only reportable by electronic file reporting.
- Report results >3.5 μg/dL within 48 hours to the Local Health Department and DPH; submit ALL lead results at least monthly to DPH only. Electronic reporting prefered.
- Report all IgM positive titers; only report IgG titers considered significant by the lab that performed the test.
- Report all bacterial isolates from blood or CSF from infants <3 days of age.
- Hospital laboratories and other providers with electronic reporting only.
- Report negative TP-PA/TPPA or FTA-ABS via electronic file.
