Direct answer
Diagnostic labs and pathology chains in India operate a dual marketing problem: B2B referrals from doctors AND B2C patient bookings. Two audiences require completely different messaging, channels, and conversion paths.
TL;DR
Diagnostic labs and pathology chains in India operate a dual marketing problem: they need B2B referrals from doctors and hospitals, and they need direct B2C patient bookings. These two audiences require completely different messaging, channels, and conversion paths. Labs that try to run a single campaign for both audiences typically underperform on both.
I'm Hanuman Sihag, Head of Innovation Chamber at ICG. This article documents the B2B + B2C hybrid funnel design ICG uses for diagnostic chain clients including Redcliffe Labs.
What is the B2B funnel for diagnostic labs?
The B2B funnel targets referring physicians and hospitals. These are healthcare professionals who make referral decisions based on lab quality, turnaround time, pricing, and relationship.
Digital channels for B2B lab marketing:
- LinkedIn: Content targeting physicians by specialty in specific cities. Content type: lab accuracy benchmarks, new test availability, technology investments.
- WhatsApp Business: A separate number and automation specifically for referring doctors, with weekly test menu updates, turnaround time reports, and direct line to a dedicated relationship manager.
- Doctor portal: A dedicated doctor login portal on the lab website where referring physicians can track their patients' reports.
- Google Ads (B2B): Targeting "pathology lab bulk reporting," "outsourced lab services hospitals," "diagnostic lab partnership India" — lower volume but extremely high conversion intent.
What is the B2C funnel for diagnostic labs?
The B2C funnel targets patients booking directly — a rapidly growing segment as health awareness increases.
Google Ads for B2C lab marketing: High-intent keywords: "blood test home collection [city]," "full body checkup [city] price," "thyroid test near me". CPL: ₹180–₹450. CPQL: ₹350–₹850.
Package marketing as conversion driver: Health checkup packages are the highest-converting B2C product. A "Diabetes Prevention Package" at ₹1,200 converts significantly better than a generic "book a test" CTA because it specifies a target audience, provides clear value proposition, and creates urgency.
ICG builds seasonal package campaigns — "Pre-monsoon health check," "Winter cardiac check," "Annual women's health package" — that consistently deliver the lowest CPL of any campaign type.
