Mass tort law firms typically evaluate claims based on four factors: medical diagnosis confirming the alleged injury, temporal relationship between product use and injury, product identification and usage documentation, and applicable statute of limitations.

Firms look for objective medical evidence including diagnostic tests, biopsy results, imaging studies, and medical records documenting the injury and treatment timeline. Pharmacy records and prescription histories are also critical.

This is why preserving medical records, pharmacy printouts, and any product packaging or documentation is important. The stronger your documentary evidence, the more likely a firm can evaluate and pursue your claim.
