Our standard TAT is 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.
1 BUSINESS DAY TURNAROUND TIME = 100% SURCHARGE (When applicable)
2 BUSINESS DAY TURNAROUND TIME = 75% SURCHARGE (When applicable)
3 BUSINESS DAY TURNAROUND TIME = 50% SURCHARGE (When applicable)
4 BUSINESS DAY TURNAROUND TIME = 25% SURCHARGE (When applicable)
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.
