DPDP Action Sheet
Use this before your next workflow goes live. It keeps the useful parts visible and turns DPDP into checks your team can actually answer.
For DPDP for Diagnostic Labs: Expert Guide, the DPDP question is how personal data enters the workflow, where it is stored, which tools touch it, what purpose was explained, and how deletion or withdrawal will work.
1. Lead Forms
Check:
- What data are you collecting?
- Is the purpose clear at the point of collection?
- Is marketing consent separate from service communication?
- Can the user withdraw consent later?
Common mistake: one checkbox that silently covers newsletters, sales calls, partner sharing and remarketing.
2. Email and WhatsApp
Check:
- Who is on the list?
- Where did consent come from?
- Is the list imported from a vendor, event, webinar, scrape or old CRM?
- Can you prove the source of consent?
Common mistake: treating every lead as permanently marketable.
3. Ads and Retargeting
Check:
- Are pixels or ad platforms receiving identifiable user behavior?
- Are audiences built from customer lists?
- Are lookalike or remarketing audiences using personal data?
Common mistake: assuming "the ad platform handles it" means your company has no DPDP responsibility.
4. Website Analytics
Check:
- Which tools run on the site?
- Are IP address, device identifiers, session IDs or form fields being captured?
- Is analytics used only for measurement, or also for profiling and targeting?
Common mistake: installing tools first and asking privacy questions later.
5. Vendor List
Make a quick list:
- CRM
- Email platform
- WhatsApp provider
- Analytics
- Ad pixels
- Form tool
- Landing page builder
- Webinar tool
For each vendor, answer: what data goes there, why, who can access it and how deletion works.
6. This Week's Action
Map one campaign from first click to final follow-up. Mark every place personal data is collected, enriched, shared, uploaded or used for targeting.
If your team cannot answer where the data came from and where it goes next, start with a data flow map before rewriting policy copy.

Managing Health Identifiers and Collection Chains
Diagnostic labs handle specific identifiers like genetic markers, biometric data, and chronic health statuses. Most labs use third-party phlebotomists for home collections, creating a chain of custody where data moves from a mobile app to a technician and finally to a Laboratory Information System (LIS). Each handoff requires a specific agreement ensuring the technician does not store patient contact details or test results on their personal mobile device after the sample is logged.
The Retention Conflict: Medical Records vs. Deletion
Labs face a conflict between medical record guidelines and the DPDP requirement to delete data once the purpose is served. You must distinguish between “medical records” (test results) and “marketing data” (patient phone numbers used for reminders). While you must keep medical reports for legal periods, you cannot retain contact info for promotional purposes if a patient requests account deletion.
| Workflow | Data Involved | DPDP Risk |
|---|---|---|
| Home Sample Collection | Patient address, GPS location, phone number | Phlebotomists retaining patient addresses on personal phones. |
| Report Delivery via WhatsApp | Patient name, age, sensitive test results | Health data visible to messaging platforms without encryption. |
| Outsourced Testing | Patient UID, specific health biomarkers | Data transfer to reference labs without a processing contract. |
| Corporate Health Checkups | Employee ID, medical history, blood vitals | Sharing individual results with HR instead of aggregate data. |
This week
Audit your phlebotomy team’s mobile phones to ensure they do not save patient contact numbers in their personal “Contacts” list or keep photos of manual requisition forms in their image galleries.
Now think about your work. Where does personal data enter your workflows? Where does it sit? Who else touches it?
Frequently asked questions
Can we still send reports to patients via WhatsApp?
You must obtain specific consent for this delivery channel and ensure the file is password-protected using the patient's unique ID. The message should not preview sensitive results in the notification bar.
Do we need a new contract for reference labs we send samples to?
Yes, you must sign a data processing agreement with any external lab that analyzes your samples. This contract must restrict them from using patient data for their own research or marketing.
How do we handle walk-in patients who refuse to give a phone number?
You must determine if the phone number is strictly necessary for the medical test or just for digital report delivery. If it is only for delivery, you must offer an alternative, like a physical pickup, rather than refusing service.
