Yes, you can sue without a confirmed diagnosis in some states through a medical-monitoring claim. That claim pays for future testing and screening after significant toxic exposure even without current disease.
The country is split on this remedy. Reed Smith reports in its review of medical-monitoring limits that about thirteen states allow these claims. The same review notes about 21-23 states reject no-injury monitoring claims.

What Is a Medical-Monitoring Claim?
A medical-monitoring claim seeks payment for future testing, not payment for illness. It covers screening after significant exposure to a toxic substance. You do not need a current diagnosis to file where the claim exists.
A standard toxic-tort injury case is different. LawInfo explains that case still requires exposure plus proof the exposure caused injury, illness, or birth defects. Causation is usually the hardest element to prove.
What Must You Prove to Qualify?
Where allowed, courts set a high bar. Morgan & Morgan explains in its guide to who qualifies for medical monitoring that plaintiffs typically must show specific facts. Those facts link the defendant conduct to a real need for testing.
You generally must prove exposure, risk, and medical need. Routine checkups do not count. The test must target the exposure-related disease and aid early detection.
- above-background exposure to a proven hazardous substance tied to defendant negligence
- significantly increased risk of serious latent disease
- early-detection monitoring exists and differs from routine care
Where Do Courts Reject No-Diagnosis Claims?
The U.S. Supreme Court limited this path in Metro-North v. Buckley. Cornell Legal Information Institute publishes the opinion holding an exposed rail worker without symptoms could not recover emotional-distress damages under FELA until symptoms appeared. New Hampshire follows the same strict view for monitoring.
MG+M Law Firm reports New Hampshire Supreme Court in Brown v. Saint-Gobain held PFOA drinking-water risk requiring testing was not legal injury. Drug and Device Law reports in its Colorado decision summary that the court dismissed an increased-risk class in Smith v. Terumo BCT. That Oct. 30, 2025 ruling treated increased risk as hypothetical future injury, not injury for standing.
What Should You Do After Exposure?
If you were exposed but feel healthy, act to protect a future claim. Save work assignments, safety notices, medical visits, and any exposure letters. Get appropriate screening promptly and follow medical advice.
Take these practical steps now. New York State Senate records in its S7474 bill page describe a 2025 monitoring proposal. The bill referred April 17 would create a monitoring claim with or without present injury. Check your state law before you assume you qualify.
- keep copies of exposure, medical, and employer records
- write dates, places, and products or chemicals involved
- ask a doctor about exposure-based screening, not only routine care
