Laboratories Providing COVID-19 PCR Molecular Testing (7-1-20) Reference Guide LA County Department of Health Services (LAC DHS) has created this guide to help organizations identify a laboratory provider that best fits their needs. This document provides an overview of some of the laboratories offering testing to LA County providers and residents.
LA County Public Health Laboratory (PHL): Diagnostic testing for SARS-CoV-2 infection is available from PHL for high priority patients and settings. View the PHL COVID-19 Testing page for PHL testing criteria and specimen instructions.

All COVID-19 associated deaths must be reported immediately by healthcare providers. All other COVID-19 cases must be reported by healthcare providers within a day. All SARS-CoV-2 test results must also be reported by laboratories within a day. Visit the Reporting page for more information.
The CDC is working with the Emerging Infections Network (EIN, Operated by Infectious Disease Society of America) to better understand reinfection, viral shedding, and immunity among patients with a history of laboratory confirmed COVID-19 disease.
Clinicians are asked to report to LAC DPH by calling 213-240-7941 from 8:00am-5:00pm Monday to Friday if they see a patient who meets the following criteria:

It remains unclear if infection with SARS-CoV-2 results in immunity and if reinfection can occur in the short term. Several reports from China and South Korea have described cases of recurrent SARS-CoV-2 RNA detection (with or without symptoms) among patients who recovered from COVID-19; whether these cases represent re-infection versus intermittent viral RNA shedding is still being determined. The extent to which such cases are occurring in the United States is unknown.
The objective of this investigation is to describe the clinical characteristics, management, and outcomes of clinician-suspected cases of reinfection to better understand the natural history of SARS-CoV-2 in the United States and guide public health action (e.g., further testing, control measures). This investigation was determined to be a public health surveillance activity (non- research). The public health emergency Paperwork Reduction Act waiver applies to the COVID-19 related data collection for this investigation. LAC DPH will facilitate submission of cases to the CDC through our health provider hotline which can be reached by calling 213-240-7941 from 8:00am-5:00pm Monday to Friday and 213-974-1234 (After Hours Emergency Operator).
