NERL Diagnostics offers its Sentry line of point-of-care control products for near patient testing in the hospital and physician office. The controls are focused on urinalysis, hemoglobin testing, and occult blood testing. The urinalysis control is a liquid, ready-to-use control that works with most urine strips and automated strip readers. The hemoglobin control, which is available in low, normal, and high levels, utilizes stabilized human red cells and offers flexible ordering of any level at any time. The Sentry occult blood control is the only commercial external control available on the market. The control works on most tests used by clinicians.
