Agricultural Diagnostic Service Center (ADSC)

The ADSC is a service unit within the College of Tropical Agriculture and Human Resources (CTAHR). ADSC conducts analyses and diagnostic tests for the people and businesses of Hawai‘i.

Services provided are:

The ADSC is a fee for service laboratory that solely provides analytical results. Specific recommendations for corrective actions based on these analytical results are ultimately prescribed by CTAHR extension agents and specialists. ADSC also handles the billing and collection of service fees.

Please do not ship samples directly to the ADSC. It is against the law to ship agricultural samples without a HDOA inspection and permit. All samples must be submitted through a CTAHR Extension Office. Current Extension Office submission and location information can be found here.
