IBL CORTISOL LIA TEST KIT by Lehnus & Associates Consulting

This is an FDA Premarket Notification (510(k)) letter for the IBL Cortisol LIA test kit. The letter itself does not contain the detailed acceptance criteria or the study results. It primarily states that the device has been found substantially equivalent to a predicate device.

Therefore, I cannot provide the requested information from the provided text because it is not present in this document. The document confirms that the device is cleared for marketing but does not detail the technical performance studies and acceptance criteria that led to that clearance.
