Best for time-sensitive collection help
Support hours: Monday–Saturday, 9:00 AM – 8:00 PM IST. We respond to emails within 24 hours, and usually much sooner.
Bookings & payments
Trouble placing a booking, applying a payment, or seeing a charge you don’t recognise? Email us your registered mobile number and booking ID and we’ll sort it out.
Reports
Reports are produced by our partner NABL-accredited labs and appear in your in-app report vault once ready. If a report is delayed or you believe it contains an error, contact us with your booking ID and we’ll follow up with the lab.
Home sample collection
Questions about a scheduled home collection, the collection agent, or timing? Reach us on phone for time-sensitive help during an active booking.
Cancellations & refunds
Most cancellations and refunds are handled automatically in the app. For anything else, email us your booking ID and we’ll respond within 24 hours.
Account & login
Can’t sign in, or need to update your phone number, email, or profile details? We can help you recover access and correct your account information.
Partners & diagnostic centers
If you’re a diagnostic center or phlebotomy partner using the Zelnoo Center or Zelnoo Phlebo apps, email us and we’ll route you to the partner operations team.
Tip: the fastest way to get help about a specific booking is to email us from your registered address with your booking ID. For app-related help, you can also reach support from the profile or help section inside the app.
