The problem

Patients call the lab all day asking if results are ready, then queue again to collect a paper envelope. The reception handles the same call a hundred times, and patients cross the city for a document that fits in a PDF.

The solution, step by step

  1. At registration, the patient consents to digital delivery and gives a WhatsApp number; a pickup code is printed on the receipt.
  2. When results are validated by the biologist, the status flips in Google Sheets and an n8n workflow notifies the patient.
  3. The patient replies with the pickup code plus date of birth; only then does the workflow send the PDF, watermarked.
  4. Results needing a conversation (flagged by the biologist) trigger an invitation to call instead of a file — the machine never delivers sensitive news.
  5. Claude drafts the daily summary for referring doctors, listing their patients' completed panels.

    6. Result and estimated gains

    • "Is it ready?" calls drop by 80%.
    • Evening counter queues shrink visibly; staff focus on sampling, not paper handling.
    • Referring doctors get same-day summaries — the lab becomes their preferred partner.
