Test Performed At:

 

 

Mayo Medical Laboratories to Miravista Diagnostics   #90019

 

Specimen Required:

 

 

Send 2.0 mL (minimum 0.5 mL) of urine from a random urine collection.

Result

Interpretation

Comment

 

 

None detected

Negative

Antigen not detected

 

 

<0.6-3.9 ng/mL

Positive, low

Results reported as <0.6 ng/mL are positive but below the lowest calibrator and cannot be quantified.

 

 

4.0-19.9 ng/mL

Positive, moderate

Quantitation is most accurate in this are of the calibration curve.

 

 

20.0->39 ng/mL

Positive, high

Results >39 ng/mL are above the highest calibrator and cannot be quantified.  Suggest monitoring antigenemia if antigenuria >39 ng/mL

Guidelines for comparing current specimen results with previous results (only results from identical specimen types can be compared).

 

 

 

 

 

 

For Low-Moderate Positives (<20 ng/mL):

 

 

Change is Ag

Interpretation

 

 

>3 ng/mL increase

Probable treatment failure/relapse

 

 

<3 ng/mL decrease

Possible treatment failure

 

 

>3 ng/mL decrease

Probable treatment response

 

 

 

 

 

For High Positives (>20 ng/mL):

 

 

Change in Ag

Interpretation

 

 

>15% increase

Probable treatment failure/relapse

 

 

<15% decrease

Possible treatment failure

 

 

>15% decrease

Probable treatment response
