Body Fluids & Reference Ranges Flashcards
Which tube of CSF is used for hematology?
Tube 3
Tube 1 = Chemistry
Tube 2 = Micro
In viral meningitis, does glucose and lactate increase/decrease/stay the same?
Normal
Protein reference range
15-45 mg/dL
150-450 mg/L
Glucose reference range (in CSF)
50-80 mg/dL
2.8-4.4 mmol/L
2/3 or 60-70% of plasma glucose
WBC and RBC reference range (in CSF)
0-5/uL
0-5 x 10^6/L
Differential in CSF (what cells would you see?)
70% lymphs, 30% monos
What would you see on CSF electrophoresis in multiple sclerosis?
Would glucose and protein increase or decrease?
Oligoclonal banding
(also would have decreased glucose and increased protein)
Volume of seminal fluid - reference range `
2-5 mL
Seminal fluid liquefaction time reference range
30-60 mins
WBC reference range in seminal fluid
<1 x 10^6/mL
<1 x 10^9/L
pH of seminal fluid - reference range
7.2 - 8.0
Motility of seminal fluid - reference range
> 50% within 1 hr
Sperm concentration - reference range
> 20 x 10^6/mL
Morphology of sperm - reference range
> 30% normal forms
Transudate vs Exudate
Transudate (transparent): originates OUTSIDE of body cavity (CHF, hypoalbuminemia, cirrhosis)
- colorless/clear/watery
- «<
- mononuclear cells in differential (lymphs, mono)
- no spontaneous clotting
Exudate: involves membranes WITHIN the cavity (infection, inflammation, malignancy, hemorrhage). Fluid that leaks out of blood vessels to surrounding tissues or cavities.
- colored (yellow, brown, red, green) & cloudy
-»_space;>
- polys in differential (neutro, baso, eosino)
- spontaneous clotting
