| Leukocyte Esterase Dipstick Test If leukocyte esterase is detected, a color change occurs on the reagent pad after the strip is dipped in the urine sample. Be sure to follow the manufacturer's directions for read-time and test interpretation. A positive leukocyte esterase test indicates the presence of granulocytic white blood cells. Lymphocytes do not contain granules, and would not produce a positive leukocyte esterase test. Positive results should be confirmed by performing a microscopic examination on the sediment; being aware that white blood cells may be absent if they are lysed, yet releasing their esterases into the specimen. Positive results may occasionally be found in random specimens from females due to contamination of the specimen by vaginal discharge. | View Page |

| Which of the following is not considered a potentially infectious body fluid for transmitting HIV? | View Page |
| Potentially infectious body fluids These substances are considered potentially infectious for an occupational exposure: blood cerebrospinal fluid synovial fluid pleural fluid peritoneal fluid pericardial fluid amniotic fluid any body fluid visibly contaminated with blood semen or vaginal fluid tissues removed during surgery. | View Page |

| The growth of the yeast-like colonies shown in the upper image was obtained on blood agar from a skin culture only in the area overlaid by virgin olive oil. The lower image is a photomicrograph of a lactophenol blue mount made from a portion of the colony. The disease associated with this fungus is: | View Page |
| Body Fluids Most Likely To Transmit HBV Body fluids most likely to transmit HBV are: Blood Semen Vaginal Secretions Pleural Fluid Peritoneal Fluid Pericardial Fluid Cerebrospinal Fluid Synovial Fluid Amniotic Fluid Blood contaminated saliva in dental procedures Any fluid visibly contaminated with blood Sweat uncontaminated by blood is not considered infectious. | View Page |
| Standard precautions continued Potentially infectious body fluids include:
Blood, Semen, Vaginal Secretion, Peritoneal, pericardial and pleural fluids, and Saliva
Sweat and tears are not generally considered infectious.
It is important to remember that bloodborne pathogens are not transmitted by casual contact, like a handshake.

| Yeast Yeast can appear as single cells or in the budding form. As single cells they can be confused with RBCs because they are about the same size. In the budding form, yeast is easily identified as demonstrated on this slide. Yeast can be found in patients with cystitis due to yeast, usually candida, or as a vaginal contaminant from patient's with vaginal candidiasis. | View Page |
| Parasites Parasites which may be found in urinary sediments include Trichomonas vaginalis, Enterobius vermicularis and Schistosoma haematobium. It is also important to note that parasites and parasitic ova may be seen in urine sediments as a result of fecal or vaginal contamination. This slide shows examples of Trichomonas vaginalis. In the female, Trichomonas is usually found as a contaminant from vaginal infection and is often accompanied by an increase in the number of white cells. Trichomonas is highly motile, measuring 5 - 15 microns with a characteristic pear shape. It has multiple anterior flagella and the nucleus is often apparent. | View Page |
| Oil or Fat Droplets Oil or fat droplets may appear as uniformly round bright globules of various sizes under high power brightfield. Oil droplets from catheter lubricants may be confused with cells, especially red cells. Lipid material from vaginal creams also forms droplets in urine. | View Page |
