COVID-19 Testing Guidance

Primex Clinical Laboratories strives to provide clients with quality testing services to better support patient health. With the ongoing pandemic, COVID-19 testing has become high in demand yet testing supplies are limited.
Because of the surge in COVID-19 testing demands, the California Department of Public Health has established new guidance directing public health officials, healthcare providers, and laboratories to follow a 4-tiered system. This system is designed to determine how COVID-19 testing will be prioritized.
Prioritized testing is based on four tiers:

Tier 1

  • Hospitalized patients with COVID-19 symptoms
  • Investigation and management of outbreaks, under direction of state and local public health departments (including contact tracing).

Tier2

  • All others with COVID-19 symptoms
  • Close contact confirmed cases
Individuals who are asymptomatic who fall within any of these categories:
  1. Live in higher risk congregate care facilities including skilled nursing facilities, residential care facilities for the elderly, correctional facilities, or homeless shelters.
  2. Work in the health care sector who have frequent interactions with the public or with people who may have COVID-19 or have been exposed to SARS-CoV-2. The health care sector includes: hospitals; skilled nursing facilities; long-term care facilities; ambulatory surgery centers; health care providers’ offices; health care clinics; pharmacies; blood banks; dialysis centers; hospices; and, home health providers.
  3. Work in a congregate care facility, including shelters for people experience homelessness and residential care facilities for the elderly.
  4. Provide care to an elderly person or a person with a disability in the home, including a person providing care through California’s In-Home Supportive Services Program.
  5. Work in the emergency services sector who have frequent interactions with the public or with people who may have COVID-19 or have been exposed to SARS-CoV-2. The emergency services sector includes police and public safety departments, fire departments, and emergency service response operations.
  6. Work in a correctional facility.
  7. Patients requiring pre-operative/pre-hospital admission screening.
  8. Patients being discharged from hospitals to lower levels of care.

Tier 3

The following individuals who are asymptomatic and fall within any of these categories:
