Questions
Hair relaxer case review, answered.
How do you prove years of product use?
We collect every receipt, photo, salon record and questionnaire answer that shows use, with pages and dates, and flag the years with no proof.
Do you cover uterine, endometrial and ovarian cancer cases?
Yes. The chronology follows whatever diagnosis the records show, with the pathology quoted as written.
Can you screen a large intake?
Yes. The same fields are pulled for every claimant: brands, years, frequency, diagnosis, date and other risk factors, ready for case selection and fact sheets.
Do you retrieve records from providers?
No. Medrecords AI does not retrieve records from providers or facilities. You bring the records you already have, and review starts in minutes from upload.
