Disclosed are methods of determining long-term deposition pattern of a compound in tissue. The following steps can be followed: placing tissue against a receptor; directing mid-infrared electromagnetic radiation onto the tissue; quantifying the electromagnetic radiation that is reflected from the tissue to obtain a reflected amount; using a calibration equation to calculate the concentration of a compound from the reflected amount; and using the concentration of the compound to evaluate presence of a clinical condition in the tissue.
