To add on a test to a specimen sample, facilities must fill out an Add-On Request Verification Form and fax it to Aculabs or call in a request. Note: Add-on requests for urine and/or stool cannot be processed. A new requisition form must be completed and a new sample must be collected and sent to the lab.

Please note that it is in Aculabs’ policy that add-on requests submitted more than 24 hours after original order date cannot be processed.
