3 diagnostic tests for vaginal fluid
- Uses litmus paper
pH test
DIAGNOSTIC TEST
Factors that can interfere with pH test
a. cervical mucus
b. semen
c. blood
d. lactic acid
e. lactobacilli
f. a and e
g. a, b, d
h. a, b, c
i. ALL
j. NONE
h. a, b, c
lactic acid from glycogen metabolism
lactobacilli is part of normal flora

MICROSCOPIC PROCEDURES
How many glass slides are used?
if gram stain is requested
3 clean glass slides
T or F
the three clean glass slides should be labelled with patient’s age and unique ID
F (should be labelled with patient’s name and unique IDentifier)
For wet mount examinations, cells and organisms are observed under what objective?
quantified per high power field (hpf) (40×)
for Gram stains, cells and organisms are observed under what objective?
reported per oil immersion field (100×)
Microscopic examination of vaginal secretion are reported like?
urinary sediment
T or F
One matter of reporting of microscope sediments found under vaginal secretion
T
3 diagnostic tests for vaginal fluid
- Observed under LPO and HPO
- Uses NSS and Vaginal fluid

- parabasal cells
- basal cells
- bacteria
- yeast
- WBCs
- Clue cells
- basal cells
- motile T. vaginalis
- hyphae/pseudohyphae

- coccobacillus bacteria attached in clusters on the cell surface
- Bacterial Vaginitis (BV) caused by
G. vaginalis
Clue cells
ORGANISMS FOUND IN VAGINAL FLUID WET MOUNTS

KOH (Potassium Hydroxide)
ORGANISMS FOUND IN VAGINAL FLUID WET MOUNTS
Determine organism
