I believe, Thyrocare, Dr. Lab like players can still get enough volumes, driven by their own campaigns and the aggregator apps like 1Mg, Pharmeasy. The forementioned local established brands have smaller number branches & won’t able to serve too many customers in metros. Also, the free home service, collection, delivery & real-time tracking will make life much easier at a more affordable cost. Indians being cost conscious & the new-gen populace being more devoid of time, these added benefits would attract them.
I reckon the inclination towards the established local brands would remain limited to elders & the conservatives, as the inquisitive young generation can quickly understand that there are not much differences between the facilities & services provided by the established and emerging players.
However, some of the aggregator apps like 1mg & Medlife has started their own diagnostic chains too, like private labels of retailers, & they are supposed to promote those more because of greater margin. Sastasundar on the other hand is not an aggregator & has its own diagnostic chain Genu Path Labs.
