How do I submit a specimen to CTA Pathology?

Specimens can be submitted via FedEx or UPS. Please address packages to 9750 SW Nimbus Ave, Beaverton, OR 97008. CTA Pathology can also provide shipping materials and labels; please contact our office if you would like to order supplies.

What do I need to submit with the specimen?

We require all biopsy submissions to include a requisition which lists all relevant clinical information and patient demographics (including patient name, date of birth, address, and insurance information). Please also ensure that the specimen container has at least two identifiers listed (e.g., the patient's name and date of birth) so we can match the requisition with the specimen.

How can I order supplies?

If you need more supplies, please email us at with your clinic's name, address, and the specific materials needed. Depending on your location, you can expect supplies to either be dropped off by one of our couriers or shipped directly to your office. You are also welcome to call us and place your order over the phone.
