P26 - Synovial Fluid Flashcards
1
Q
thixotropism (3)
A
- formation of semi-solid gel when synovia cools
- semi-solid gel becomes liquid again upon shaking
- due to presence of mucin
2
Q
physical characteristics of synovia
A
- color
- transparency
- viscosity
3
Q
biochemical analysis of synovia
A
- protein concentration
- mucin clot test
4
Q
TNCC of synovia
A
- diluent (saline not acetic acid)
- thixotropism may prevent accurate dilution
5
Q
pink color of synovia
A
- pathologic hemorrhage or iatrogenic
6
Q
deep yellow of synovia
A
- bilirubin formation in chronic hemorrhage
7
Q
hazy or cloudy of synovia
A
- inflammatory cells
8
Q
mucin clot test collect in what tube
A
- red top
9
Q
causes of poor viscosity
A
- hyaluronidase-producing bacteria
- inflammation
- dilution
10
Q
collect synovia in what type of tube
A
- EDTA - prevents fibrin clots
11
Q
windrow formation
A
- because of the mucin in the synovia
12
Q
cytological features of synovia
A
- windrow formation
- mononuclear cells (95%)
13
Q
appearance of hemarthrosis
A
- bloody
14
Q
protein concentration of hemarthrosis
A
- increased
15
Q
TNCC of hemarthrosis
A
- increased
