A missed or delayed diagnosis can begin after a test is ordered. The test may not be completed, the result may not reach the responsible team, an abnormal finding may not be recognized or communicated, or a recommended repeat test, referral, or treatment may not occur. A legal review should identify the exact breakdown instead of treating every incorrect diagnosis as the same event.

A diagnostic result can be generated, posted, and even viewed without the follow-up loop being complete.

Map the result from order through completed action

  • Why the test or referral was ordered, the working diagnosis, urgency, instructions, expected completion time, and who was assigned to track it
  • Scheduling, specimen collection, performance, processing, preliminary and final result times, abnormal or critical flags, addenda, and corrected reports
  • Which clinician, team, or system received the result; acknowledgments, inbox activity, routing, coverage, handoffs, portal release, calls, letters, and failed contact attempts
  • Interpretation, communication to the patient, repeat testing, treatment, referral, escalation, safety-net instructions, and confirmation that the next step occurred

Use diagnostic-safety research to identify the process stage

An Agency for Healthcare Research and Quality diagnostic-safety issue brief describes three testing areas relevant to diagnostic error: ordering and processing tests, interpreting and managing results, and closing the loop on follow-up and communication. That framework helps organize the record; it does not establish the legal standard for an individual provider.

Do not assume that portal release completed communication

A portal timestamp may show when information became available to a patient, not whether a clinician reviewed the result, explained its meaning, assessed urgency, ordered the next step, or confirmed follow-up. Conversely, the absence of a phone call does not by itself establish negligence if another appropriate communication and action process was documented.

HHS medical-record access guidance explains the patient's general right to obtain records from covered providers and plans. Request the result itself and the surrounding order, communication, referral, follow-up, and later-care records. If entries conflict or appear to have changed, the related medical-record discrepancy guide explains how to preserve versions and seek source-level information without assuming misconduct.

Separate a process gap from compensable harm

  • What information was available at each point and what a qualified reviewer says reasonable care required in those circumstances
  • The specific missed action: review, interpretation, communication, repeat testing, referral, escalation, treatment, or confirmation
  • When the condition probably would have been identified with the alleged appropriate action
  • Which treatment or management option was realistically available then and how the outcome probably would have differed
  • Underlying disease, progression, patient-specific factors, later events, and other explanations for the claimed injury

Apply North Carolina proof and filing rules

G.S. 90-21.12 provides the standard-of-care framework for covered medical-malpractice actions. Rule of Evidence 702 addresses expert testimony, including additional requirements for testimony on a medical standard of care. Rule 9(j) generally requires qualified review of the available care and records before filing a complaint alleging failure to meet that standard.

Preserve the record before systems change

Save patient-facing portal material with dates, but do not rely on screenshots alone. Request the designated record set and ask counsel or a qualified reviewer which native data, audit controls, routing history, image files, outside records, referral records, or testimony may be material. Avoid changing, annotating, or publicly posting the original medical information.
