Service Providers for SARS_CoV-2
The SARS-CoV-2 test detects the presence of the virus that causes COVID-19, typically using a nasal swab, saliva sample, or throat swab. Preparation may include avoiding eating or drinking for a short time before the test. During the test, a healthcare provider collects the sample, which may cause mild discomfort. Results are typically ready in 24-48 hours, depending on the test type. Positive results indicate infection; negative results suggest no current infection. Conditions like recent exposure or vaccination status can influence results. False negatives or positives are possible, so follow-up testing may be required in some cases.
