Positive tests for NG and CT in patients evaluated for sexual victimization may represent infection from sexual contact, contiguous spread of infection, or the presence of infected assailant secretions. Relying on patient reports of symptoms, or types of sexual contact, to determine need for testing may miss NG and CT infections in patients evaluated for sexual victimization.

In our experience the test instrument was simple and easy to operate. It met the specification for precision and accuracy, its measurements were highly linear, and it maintained a stable calibration for one year. If the cuvettes are filled as soon as blood is drawn, anticoagulation is unnecessary. However, the cuvettes should be read with 1 min of filling the cuvette.

What are the health implications-if any at all-when a source begins to present substantial concentrations of sodium? The answers are still largely hypothetical.

Oxicom oximeters are widely used in cardiac catheterization laboratories. To calibrate the Oxicom oximeter, samples of oxygenated and deoxygenated whole blood are first analyzed on a CO-Oximeter, and then the Oxicom is adjusted to agree with the CO-Oximeter's readings. Subsequently, the Oxicom's calibration is confirmed at frequent intervals by taking readings from a white plastic stick that is inserted into the instrument to simulate a blood sample. The data in this report demonstrate that the readings from the white plastic "test simulator" failed to detect an out-of-calibration condition. By contrast, when the Oxicom was carefully adjusted to agree with a CO-Oximeter's readings on arterial and venous blood, a linear calibration curve resulted, and the Oxicom achieved its specified accuracy (2.5%). The precautions necessary to calibrate the Oxicom correctly are enumerated in the text.
