Litholink’s At-Home Collection kit produces laboratory results that require a Litholink test request form (lab order) from your medical provider. If you have a Litholink test request form (lab order) you can request your At-Home kit through LabCorp’s patient portal. Requesting a kit without a test request form or lab order may result in your samples being rejected and/or you being held accountable for the full testing cost.
