Merge referral letters with lab PDFs the specialist portal accepts as one file

Patients carry imaging exports and typed referrals—many portals cap uploads to a single PDF.

Specialist intake systems often reject multiple attachments even though primary care sends the referral, labs, and imaging notes separately. Merging keeps the clinical narrative in the order triage nurses expect.

Index order matters

If the cover lists exhibits A–C, merge in that exact sequence. File pickers that sort alphabetically can place labs ahead of the referral unless you add zero-padded prefixes.
