Test Fees

Effective October 1, 2022, the NSL hourly rate is $110/hour.

Laboratory customers track results by sample; therefore, NSL charges customers by the test.  Test fees are based on the hours required to perform the test.

  • Test fees = $110/hour x hour(s)
  • Hours range from 0.05 to 4.75

NSL performs over 150 tests. 

  • Fees are based on the test specifications requested by the customer.
  • The hours required to perform the test reflects the labor required for the test. 
  • Factors that can impact hours include sample type, packaging, preparation, and volume; method adjustments; extraction and clean-up; number of analytes; data acquisition and analyses; and variations in reporting.

Test fees are communicated to the customer upfront and documented through an agreement prior to testing.
