Human Immunodeficiency Virus (Hiv)/Hepatitis B Virus (Hbv) Risk Perception Related To Needlestick Injuries At A Medical School In Norfolk, Virginia, Ronald B. Hartman

Community & Environmental Health Theses & Dissertations

A limited number of studies have been conducted to assess the perceptions of risk of medical students and residents for acquiring Human Immunodeficiency Virus (HIV) or Hepatitis B Virus (HBV) via percutaneous (needlestick) injuries while performing clinical training. The purpose of this study is to investigate these perceptions of risk, and to determine whether there is an association between a high perception of risk and a low incidence of needlestick injury. The method of investigation was a four-page survey questionnaire. The instrument was investigated for reliability by use of a pilot study with a small group of medical students and …

Comparison Of Positive Screening And Confimatory Results From Federally Mandated Drug Testing Of Urine, Mary M. Stuck

Community & Environmental Health Theses & Dissertations

The purpose of this study was to analyze the accuracy of FDA approved immunoassays for the detection of drug positive urine samples.

Federal civilian employees are tested under the strict protocol of the Department of Health and Human Services mandatory guidelines for federal workplace drug testing programs. The guidelines provide for a two instrument testing protocol for the analysis of urine samples. The first is an FDA approved immunoassay. Samples which test positive on this screening immunoassay are then submitted for confirmatory testing with the "gold standard" gas chromatography/mass spectrometry.

A Test Of An Alternate Calibration Matrix For Niosh Method 7300, Robert T. Vitek

Community & Environmental Health Theses & Dissertations

The purpose of this study was to determine if the analytical results (when determining cadmium, lead, and zinc concentrations) for air sample filters prepared and analyzed according to N:OSH Method 7300, differ significantly, from those obtained when the instrument is calibrated using EPA Method 200.7 acid matrix standards. The null hypothesis was that no statistically significant difference, measured at the 95% confidence level, would exist between results obtained from the two calibration standards. Careful standard and sample preparation, the use of an internal standard, and the application of working standard and working internal standard correction factors served to isolate the …
