Study Set Content:
Phenol derivatives found in certain intravenous medications produces what color
Green
may occur in catheter bags and is caused by indican in the urine or a bacterial infection,
Purple Staining
A purple staining is frequently caused by what species
Klebsiella and Providencia
refers to the transparency or turbidity of a urine specimen
Clarity
determined by holding the urine in front of a light source; assessed along with urine color
Clarity
Few particulates, print easily seen through urine
Hazy
No visible particulates, transparent
Clear
Many particulates; print blurred through urine
Cloudy
May precipitate or be clotted
Milky
Print cannot be seen through urine
turbid
RBCs, WBCs; Contaminants includes powders, talc, creams, lotions, feces, etc.
Hazy/ Slightly Cloudy
Crystals of solutes; Epithelial Cells; Fats; Microbes;
Cloudy
Mucus, mucin, pus; Radiographic contrast media; Semen, spermatozoa, prostatic fluid
Turbid
Usually clear; Precipitation of amorphous phosphates and carbonates may cause a white cloudiness; bacterial growth can cause urine to be cloudy
Normal Clarity
presence of squamous epithelial cells and mucus; improperly preserved urine
Non-pathologic Turbidity
Non-pathologic turbidity refrigerated specimens:
- White precipitate
- brick dust precipitate
- semen, fecal contamination, radiographic contrast media, talcum powder, and vaginal creams
RBCs, WBCs and bacteria
Pathologic turbidity
abnormal amounts of non-squamous epithelial cells, yeast, abnormal crystals, lymph fluid, and lipids (least common)
Pathologic Turbidity
bacteria + WBCs + casts
Upper UTI
bacteria + WBCs - casts
Lower UTI
