L A County Department of Public Health: Information for Healthcare Providers
Please read these instructions carefully as issues with specimens, forms, and labeling can lead to specimen rejection or testing delays. DO NOT collect or send specimens to the Public Health Lab (PHL) until instructed to by DPH. When contacting DPH, please be prepared to provide a call-back number and to wait for 10-15 minutes for a call-back. Once approved by DPH, follow all instructions below under Public Health Lab Specimen Collection and Transport.

PHL aims to result tests within 2 business days of receipt of specimen, but delays could occur based on volume and capacity.

Laboratory Testing

For all patients: Collect TWO upper respiratory specimens - one oropharyngeal (OP) swab and one nasal specimen (either nasopharyngeal (NP) swab, nasopharyngeal wash/aspirate or nasal aspirate swab)

For patients with a productive cough: collect one lower respiratory specimen (sputum, bronchoalveolar lavage or tracheal aspirate) in addition to the upper respiratory specimens.

Outpatient settings should only collect an NP and an OP swab.

Information for Patients Managed at Home and Their Caregivers

Non-hospitalized patients being tested for COVID-19 should be instructed to self-isolate. Patients should follow home isolation instructions until their test result is negative or until they are told by LAC DPH or their healthcare provider that they are no longer infectious.

Infection Prevention Including Personal Protective Equipment

Updated 3-7-20: Interim US Guidance for Risk Assessment and Public Health Management of Persons with Potential Coronavirus Disease 2019 (COVID-19)

Exposures: Geographic Risk and Contacts of Laboratory-confirmed Cases.

On 3-10-20, the CDC published revised guidance, Interim Infection Prevention and Control Recommendations for Patients with Suspected or Confirmed Coronavirus Disease 2019 (COVID-19) in Healthcare Settings. Below is a summary of important changes to PPE and patient isolation.

For more information please visit:

CDC guidance recommends the following changes in personal protective equipment (PPE) for healthcare workers caring for patients with suspected or confirmed COVID-19. Facemasks are an acceptable alternative to respirators in the setting of shortages of respirators.

N95 respirators should be prioritized for procedures that are likely to generate a high concentration of respiratory aerosols (e.g., intubation, cardiopulmonary resuscitation).

Eye protection is still recommended for use during patient care.

Gowns and gloves are recommended for clinical care, but if gowns are in short supply, they should be prioritized for procedures that are likely to generate respiratory aerosols.

Assure Adequate Supplies of N95 Respirators

In the setting of a respirator or mask shortage, healthcare facilities can apply for additional supplies through the mechanisms below.

Facilities that are part of the Reddinet should send requests through that system.

Healthcare facilities and clinics not part of Reddinet can complete the request form Resource Request Medical and Health (2018) and email it to
