Our standard TAT is 5-7 business days or later for most tests. For test results needed in less than 7 business days, rush charges may apply. A & B Labs will provide the TAT on each quote.

Rush charges may apply to the tests, if needed and/or specified that the test must be rushed. Rush charges will only apply to those tests in which rushing the sample testing implies an actual cost.

Sample matrix may affect feasible turnaround time

Note for Asbestos: A prep charge fee will be incurred if the samples are prepped but not able to be analyzed due to step rules for overloading. Bulk PLM that requires a separate report and analysis for individual layers will be charged accordingly, per layer.

A & B Labs will pay for the outgoing sample kit shipment costs if the kit order is received 5 business days in advance by using the most cost effective means of shipping available (Examples: UPS Ground Service, FedEx Ground, FedEx Express 3 Day, etc…). For International shipping, the client is responsible for shipping costs both outbound and inbound.

A & B Labs can provide sample media (at cost with a surcharge) provided the laboratory is given at least 5 days notice. Routine kits include PVC filters, MCE filters, sorbent tubes, chain of custody forms and Federal Express return shipment forms with A & B Labs’ ID number. Other media, pumps and related equipment are available for additional charges. All sample media will be charged to the client immediately after the media kit is ordered or given to the client.
