Urinalysis is the most commonly used method of assessing and monitoring of the patient in urological practice. 

Objective: to estimate the diagnostic value of the portable urine analyzer "ETTA AMP-01" for subsequent use as a tool for patient-centered urology (mHealth) with proven efficacy. 

Materials and Methods. Results of 109 patients urine analysis performed with a portable urine analyzer ETTA AMP-01 and standard tools of laboratory examination were compared. Protein, urobilinogen, erythrocytes, leukocytes, ketone bodies, glucose and nitrite were identified. We assessed diagnostic consideration, sensitivity and specificity; all results are staistically reliable. Corresponding rates in comparison to standard laboratory methods are as follows: protein 0.69, 46.77%, 100.00%; urobilinogen 0.98, 40.00%, 100.00%; erythrocytes 0.91, 74%, 93.55%; leukocytes 0.85, 67.35%, 100.00%; ketone bodies 0.98, 71.43%, 100.00%; glucose 0.99, 66.67%, 100.00%; nitrites 0.96, 100.00%, 95.79%. 

Diagnostic accuracy: 0,69-0,99 (> 0.9 for 5 out of 7 indicators). 

The specificity of the analyzer: 93,6100,0% (average 0.99 ± 0.03). What characterizes the analyzer to be more specific than sensitive diagnostic device that is common to many screening tools. 

Conclusion. Studied method is a specific diagnostic test with high predictive value and diagnostic accuracy.
