The time required to obtain ELISA test results varies depending on the specific test, laboratory, and the workload of the facility. In general, ELISA tests may provide results within a few hours to a day. Some rapid ELISA tests designed for point-of-care diagnostics can deliver results in as little as 15-30 minutes. However, more complex and specialized ELISA assays may take longer due to additional steps or the need for confirmation and validation. It's essential to check with the testing facility or healthcare provider for an accurate estimate of result turnaround time.
