What is the most accurate COVID-19 test?
"The most reliable test is the test with nasal swab," said Houston's Health Authority Dr. David Persse. "That takes a minimum of 24 hours to get back." Nasal PCR tests are tests where a swab is inserted into your nose and the sample is then sent off to a lab to be analyzed. Because the analysis is done at a lab, the process takes longer, however, it is considered the "gold standard" of tests.
What happens when someone receives a positive result?
Those with manageable symptoms should stay home and avoid all person-to-person contact until symptoms subside, Persse said. Health care providers can monitor symptoms remotely and determine when a patient has returned to health. Those who have come in contact with that person may be able to seek out testing at certain sites, even prior to their test results coming in. If conditions worsen, Persse said to seek medical advice and call ahead if going to an emergency department.
What about the 15 minute test we see everywhere?
"The quick test, there is one with Abbott labs now. If you get a positive result, that's reliable," said Dr. Persse. "However, if you get a negative, that is not reliable at all because there's a high negative with that particular test."
Why are the 15-minute tests not considered that reliable?
"They're just not as accurate," said Dr. Ed. Rensimer, an infectious disease doctor who is doing testing at his office. "They're doing them quickly and the products that are out there right now just haven't proven to be as sensitive." Dr. Rensimer adds that if you are symptomatic, get a rapid test. He said if it's negative, get a second opinion. At that point, you should also get a nasal PCR test, which may very well come back positive.
What kind of tests are being offered at the free testing sites?
Most of the free test sites, including ones run by the City of Houston, State of Texas, Harris County, and various other locations, are PCR lab tests. The time to get results back are anywhere from 24 hours to four or five days.
Is there a difference between free sites and private testing that costs money?
Generally, no. Most nasal swab tests are sent to the major labs Quest and Labcorp, whether they are government-run sites or testing in your doctor's offices. The quick tests are mostly offered at standalone emergency room locations, and costs range from $80 to $150, although they are sometimes covered by insurance. Some doctors are also offering sputum tests, where the patient's spit is tested for the virus.
Does the coronavirus test cost anything?
Tests administered through Harris County and the city of Houston are free. Tests offered by private providers are paid through insurance or out-of-pocket payment. Some sites operated though public-private partnerships or at federally qualified health centers also offer free tests for those without health insurance. For payment and testing access questions, residents are encouraged to contact their primary care physicians or local coronavirus hotlines.

Where can I get a coronavirus test?
There are two types of testing locations:
Walk-up testing: Some tests are available at health clinics, some CVS pharmacies, urgent care centers, free-standing emergency rooms and hospitals. Those with non-life-threatening symptoms who are seeking on-site testing should call primary care physicians for a consultation first, Harris County Public Health officials recommend. This gives health care providers time to prepare to administer a test by wearing protective clothing and isolating a patient before they come in contact with others.
Drive-thru testing: Large-scale testing sites are now being offered by both private and public providers. Government-funded tests are free to those with and without insurance. Some test centers require prescreening, while others perform screening on-site.
