WhatsApp message templates for blood banks and diagnostic centres
A blood bank or diagnostic centre needs five utility templates and one marketing template. Appointment confirmation, home collection details, preparation instructions, sample received and reports ready are utility because the patient booked the test; a donation camp invite is marketing because the patient did not ask for it.
A diagnostic test is a transaction with a nervous middle: the patient is unsure what to do before it and anxious about the result after it. Both moments generate calls. Messages that carry the preparation rules and then the report close the loop without a single ring.

- Every template is submitted under one category, and Meta assigns the final one in review. A utility template that reads like a promotion can be reclassified as marketing, which changes both the rate and the opt-in requirement.
- Since 1 October 2026, service messages are charged per delivered message after the first 1,000 free service messages per business phone number per month. The allowance does not roll over and there are no volume tiers.
- Inbound messages are free, and a customer-initiated message opens the 24-hour customer service window. Anything you start outside that window needs an approved template.
