A system and method for detecting perforations in a body cavity. In accordance with the method of the invention, a fluid (liquid or gas) is delivered into a body cavity to slightly pressurize the cavity. A pressure sensing system monitors the pressure within the cavity for a predetermined test period. If cavity pressure is not substantially sustained during the test period, the physician is alerted to further assess the cavity for perforations before initiating treatment within the cavity. In a preferred form of the system, a medical treatment system such as an RF ablation system is provided with perforation detection functionality. The system preferably includes a pre-test and post-test lockout system. The lockout system prevents RF power delivery unless, during a predetermined test period, the pressure sensing system determines that no perforation exists, or unless a previously performed perforation detection procedure determined a perforation was present but the lockout system was subsequently overridden by the physician.

A method and apparatus for use in respect of samples which are assessed for quality prior to testing in a clinical analyzer. The method and apparatus identify parameters such as gel level and height of fluid above the gel in blood samples, where appropriate, for the purposes of positioning the specimen for determination of interferents. Such interferents include hemoglobin (Hb), total bilirubin and lipids. These interferents are determined by measurement of absorption of different wavelengths of light in serum or plasma, or other specimens, which are then compared with values obtained through calibration using reference measurements for the respective interferents in serum or plasma or other type of specimen. Determinations of temperature of the specimen, as well as specimen type, for example whether the specimen is urine or plasma or serum, may also be carried out.
