42 CFR 37.97: Notification of spirometry results.

(a) Findings must be communicated to the miner or, if requested by the miner, to the miner's designated physician. The health care professional at the NIOSH-approved facility must inform the miner if the spirometry shows abnormal results or if the respiratory assessment suggests he or she may benefit from the medical follow-up or a smoking cessation intervention.

(b) NIOSH will notify the miner of his or her spirometry test results, a comparison between current and previously submitted spirometry tests (if available), and will advise the miner to contact a health care professional as appropriate based on the results.
