Deven Choksey, managing director, KR Choksey Shares and Securities, adds that while margin deterioration is a concern, these firms could protect their margins by bringing in segmentation and increasing footfalls.

Dr Lal PathLabs also faces a concentration risk as 70% of its revenues come from North India, largely Delhi and NCR. While the company plans to open reference labs in the East and Central India, it remains to be seen if it can scale up business in those regions.
