Coronavirus Environmental Swab Testing

Environmental Coronavirus Swab Testing

Real-Time Polymerase Chain Reaction (RT-qPCR)

A&B Environmental Services, Inc. (A&B Labs) has expanded its microbiological analytical services to include testing of environmental swabs to detect the presence of RNA from SARS-CoV-2.

The environmental swabs will be analyzed by Real-Time Polymerase Chain Reaction (RT-qPCR) following standard techniques. The standard turnaround time is 4 business days from receipt of the samples. Expedited analyses (including same day) are available upon request with surcharges to be applied accordingly.

The collection process requires using a swab provided by the lab. The sampler will remove the swab from the shipping container near the location where the sample will be taken. Swab the surface at an angle, making sure that a majority of the swab tip touches the sampling area then place immediately into a labeled 1.5 mL tube that is provided in the kit. The swab will need to come into complete contact with pre-aliquoted solution which will extract any RNA from SARS-CoV-2 that was picked up on the sample swab and inactivate the virus in the buffer.
The swabs will stay moist in the transport tube for up to 24 hrs and should to be shipped back to the lab below 6°C.

This test is not suitable for analysis of samples obtained from biological sources.
