Test Results

Your lab test will be analyzed using state-of-the-art instruments and equipment. Results will be reviewed by medical doctors (Pathologists) with years of experience interpreting and diagnosing a broad range of conditions.

Your results will be released as soon as possible. If you have a CHA provider and use MyChart, you may be able to get results faster. Most lab results are released to your MyCHArt account about 72 hours after results are final. Radiology results are not available on MyCHArt.
