What to Expect During COVID Testing

A care team member will ask about your symptoms and health history. A clinician can then determine which test may be appropriate and whether additional evaluation is needed. COVID-19 and flu symptoms can overlap, so combined testing may be useful when a provider recommends it.

Palm Urgent Care offers rapid COVID-19 testing and rapid influenza A and B testing. Most rapid results are ready during the visit. If a send-out PCR test is needed, results usually return within 24 to 48 hours. Timing can vary, so ask the care team about the test being used and its expected turnaround.

Testing options can include:

  • Antigen tests: Often provide rapid results. A negative result may not rule out infection.
  • NAAT or PCR tests: Detect viral material and may be used when a more sensitive test is appropriate.

The CDC's COVID-19 testing guidance explains that a single negative rapid antigen result does not always rule out COVID-19. If you have symptoms and your antigen test is negative, follow current guidance on repeat testing or ask a clinician whether another test is appropriate.

When to Consider a COVID Test

Consider contacting a healthcare professional about testing if you have symptoms such as:

  • Fever or chills
  • Cough, sore throat or congestion
  • Fatigue or body aches
  • Headache
  • Nausea or other new symptoms

Testing may also be useful after an exposure or when documentation is needed for work or school. Your clinician can discuss the timing of a test, especially if you recently had COVID-19 or have a health condition that increases your risk of severe illness.

A test result is one part of care. If you test positive, a provider can review your symptoms and discuss treatment options when appropriate. If you are at higher risk for complications, contact a clinician promptly to ask whether early treatment may be suitable.

Other Walk-In Testing and Services

COVID-19 testing is one of several services available through Palm Urgent Care. Depending on the clinic, the reason for your visit and clinical evaluation, services may also include:

  • Flu testing for influenza A and B
  • UTI testing for urinary symptoms
  • H. pylori testing for certain stomach concerns
  • X-ray imaging to evaluate some injuries or symptoms
  • EKG testing to assess heart rhythm when clinically appropriate

Availability may vary by location. Call (619) 354-4694 to ask about a specific service before traveling. A clinician can help determine whether a test is suitable for your symptoms.

Insurance and Cost

Palm Urgent Care accepts Medi-Cal, Medicare and major insurance plans. Coverage for COVID-19 testing can depend on your plan, symptoms, exposure history and the type of test. Contact your insurer or call the clinic to check your benefits and any expected cost.

Self-pay patients are welcome. Call ahead to ask about current pricing for the test you need. Bringing your insurance card and identification can help the team verify your information during check-in.

When to Seek Emergency Care

Urgent care can assess many non-emergency illnesses. Seek emergency care instead for severe trouble breathing, persistent chest pain or pressure, new confusion, difficulty waking, or pale, gray or blue lips or skin. Call 911 for a medical emergency.
