This is the preferred screening method for fecal occult blood.
Guaiac
This is the pH range for normal vaginal secretions.
3.8-4.5
This test on vaginal secretions must be performed prior to placing the swab in saline.
pH
Ingesting high amounts of this substance will cause a false negative result with the gFOBT.
Ascorbic acid
Stool from an upper GI bleed would appear as this.
Black, Tarry
The FOBT that is not affected by nonhuman sources of blood, such as red meat.
Immunochemical
This is the group of organisms that make up a majority of normal vaginal flora.
Lactobacilli
This test is considered positive if a "fishy" odor is detected.
Amine test
This term is used to describe the presence of excess fat in the feces.
steatorrhea
This is the characteristic appearance a stool exhibits in cases of bile duct obstruction.
Pale, clay-colored; sometimes bulky or frothy
When performing the APT test, the supernatant will be this color if fetal blood is present in the feces or gastric specimen.
Pink
This test is performed on vaginal secretions to dissolve RBCs and epithelial cells, and leave fungal elements intact.
KOH prep
State the condition for which culturing vaginal secretions is not helpful in making a diagnosis.
Bacterial vaginosis
This FOBT uses the pseudoperoxidase activity of hemoglobin to detect occult blood in the stool.
Guaiac
This disorder presents with white, "curd-like", discharge.
Candidiasis
This test is performed on feces to determine if leukocytes are present. (Not looking for the microscopic examination for leukocytes)
Fecal lactoferrin test
The condition in which vaginal secretions typically exhibit a normal pH level.
Candidiasis
A "strawberry" cervix is a characteristic of this vaginal disorder.
Trichomoniasis
This fecal test requires that patients eat red meat during the collection period.
This vaginal disorder presents with sections that appear yellow-green, frothy, and adherent.
Trichomoniasis
If you have stained the fecal specimen with 10% eosin-alcohol what test are you performing?
The two conditions in which the amine test typically yields a positive result.
Bacterial vaginosis and trichomoniasis
This is an acceptable swab to use when collecting vaginal secretions.
Polyester tip with a plastic shaft
This stain is used when examining the stool for fecal fats.
The use of oral antibiotics may cause the stool to appear this color due to the oxidation of fecal bilirubin to biliverdin.
