Turbidity
|
|
Interpretation
|
Negative
|
0 =
no turbidity ( 0 mg/dL)
|
|
|
Trace
= < 30 mg/dL
|
Trace
= slight turbidity
(1-10 mg/dL) |
|
|
1+
= 30 mg/dL
|
1+
= turbidity through which print can be read (15-30 mg/dL)
|
|
|
2+
= 100 mg/dL
|
2+
= white cloud without precipitate through which heavy black lines on white
background can be seen
|
|
3+
= 300 mg/dL
|
3+
= white cloud with fine precipitate through which heavy black lines cannot
be seen (150-300 mg/dL)
|
|
|
4+
= 2000 mg/dL
|
4+
= flocculent precipitate
(> 500 mg/dL) |
