2. green or yellow green


3. White or pale gray; red color

Why must cell counts and smears or body fluids be prepared withing 30 minutes of collection?

After 30 minutes, WBC begin to deteriorate.

In what condition will the CSF have increased lymphocytes, increased protein and lactate but decreased glucose?

Fungal meningitis

Why is the alpha feto protein test performed on aminotic fluid and what is the confirmatory test?

Neural tube defects and acetylcholinesterase

What type of fluid is non-inflammatory, colorless, and clear, with a S.G. < 1.015, protein < 3 g/dL with no spontaneous clotting, LDH < 200 IU/L, WBCs < 1000/uL, predominantly mononuclear cells?

Transudate

What tests are performed on all body fluids?

Color, turbidity, cell counts and differentials

Cytocentrifugation, which produces a monolayer of cells in a small button.

What carbohydrate powers sperm motility and what reagent is used in its screening test?

Fructose is the carbohydrate and resorcinol is reagent

What organs are involved in the production of semen?

The epididymis, seminal vessels, prostate and bulbourethral glands

What quality control is required on a cytocentrifuge?

Check its speed with a tachometer and its timer with a stopwatch every month.

What test can be used to differentiate amniotic fluid from maternal urine?

Fern Test
