Patient portals store data.
They do not manage trends.

Most healthcare portals were built to share records, not to track what happens between visits.

What most portals do

  • Show lab results
  • Store visit notes
  • Allow patient-provider messaging

What most portals do not do

  • Collect structured daily symptom data
  • Track trends across weeks or months
  • Detect early deterioration
  • Convert patient inputs into clinical summaries

Portals are archives.

Merina is an early-detection system.

A portal that shows your lab result from last month does not tell your doctor that your pain has been increasing every week since then.

A portal that stores your medication list does not tell your doctor that you have been missing doses three days a week.

These are the signals that matter most in chronic care. They live in the gap between visits. Today, that gap is empty.
