Executive summary
A diagnostic center in Nashik doing around 800 patients per month had noticed that home collection patients — over 35% of their volume — were significantly less likely to return than walk-in patients. ReviewsFlow built a home collection-specific care sequence: a post-visit feedback request, a service personalisation message from the phlebotomist's team, and a family wellness follow-up 60 days later. Within two quarters, home collection repeat rate rose from 21% to 62%.
The challenge
Home collection patients were convenient for once — then gone
The center had invested heavily in home collection infrastructure (phlebotomist training, GPS scheduling, cold chain handling) and was pricing it competitively. But the data told a different story: home collection patients showed up for their first visit and rarely came back. The most common follow-up path was simply to call a competitor's collection service when the next test was due.
What ReviewsFlow built
ReviewsFlow identified that home collection patients needed a different post-visit narrative: one that felt personal, acknowledged the service experience (not just the test), and created a family wellness context for the next touchpoint. The sequence included a phlebotomist care message, a report-ready notification, a feedback request, and a 60-day family wellness nudge personalised to all household members who had previously tested.
The personalisation that unlocked trust
The breakthrough was the phlebotomist care follow-up: a WhatsApp message sent 2 hours after sample collection, identifying the patient by name and the collection team — 'Ramesh from our home collection team visited you this morning. We hope the experience was comfortable.' Combined with a same-day report notification, it created a service continuity experience that home collection patients were not used to.
Results
Our home collection patients are now our most loyal customers. The personalised messages made them feel cared for — like a doctor's office, not just a test service.
