Annual Check-up Reminder SMS Template for Diagnostic Labs
A ready-to-adapt SMS message for diagnostic labs and pathology centres, with placeholders, sample values and compliance notes.
When to Send This Message
Send to opted-in patients about a year after their last health package. For diagnostic labs and pathology centres, this is one of the everyday messages that keeps patients informed without a phone call. It can be sent manually from a panel at first and automated later through an API.
Diagnostic labs win business through doctor referrals, home sample collection and convenience.
The SMS Template
India (DLT format)
[Business Name]: It has been a year since your last health check-up. Book your annual check-up before {#var#} with free home collection. Call {#var#}.
To opt out, SMS STOP to [opt-out number].International (plain text)
[Business Name]: It has been a year since your last health check-up. Book your annual check-up before {date} with free home collection. Call {phone}.
Reply STOP to opt out.Example with sample values
[Business Name]: It has been a year since your last health check-up. Book your annual check-up before 31 Oct with free home collection. Call 0755-XXXXXXX. To opt out, SMS STOP to [opt-out number].
With these sample values the message is 200 characters in the standard GSM-7 character set, which is 2 SMS parts (square brackets count as two characters each). Long links or local-language (Unicode) text increase the count, as Unicode SMS allow 70 characters per single part.
Replace [Business Name] with your registered brand name. Links shown use example.com as a placeholder; use your own domain.
Placeholders and Sample Values
| Placeholder | Meaning | Sample value |
|---|---|---|
| {#var#} | Date | 31 Oct |
| {#var#} | Phone | 0755-XXXXXXX |
Filling in each placeholder
- Date (sample: 31 Oct): Write dates in an unambiguous form such as 14 Oct or 14 Oct 2026; avoid formats like 10/11 that customers read differently.
- Phone (sample: 0755-XXXXXXX): Use a number the customer can actually reach during business hours, ideally one already shown on your website.
This template has 2 placeholders and a body of 149 characters before values are filled in. Shorter messages cost less and are more likely to be read in full; aim to keep the filled-in message within one or two SMS parts.
Category and Approval
In India this is a Promotional template. It can only be sent to customers who have not blocked promotional messages, within the permitted time window, from a promotional header. Include an opt-out instruction as required by your operator.
Compliance Checklist
- Promotional versions are sent only within the permitted hours and only to recipients who have not opted out.
- The header (sender ID) and the template are registered on a DLT platform, and the template text matches exactly, apart from the variables.
- Each {#var#} holds only the kind of value it was registered for; most platforms limit each variable to 30 characters.
Rules to keep in mind for Diagnostic Labs
Labs should describe tests factually and avoid diagnostic claims in ads. Reports contain health data, so links must be secure and shared only with the patient or the person they authorise, in line with the DPDP Act, 2023.
General guidance, not legal advice. Rules change, so confirm current requirements before launch. See our SMS compliance guide for India.
Tips for Better Results
- Make the offer specific and honest, with a clear end date and any conditions stated.
- Limit frequency; a few relevant messages perform better and attract fewer opt-outs than frequent broadcasts.
