Guidelines to patient preparation for sample collection for spot (morning) urine analyte test

  1. The examination uses the morning urine portion.
  2. To collect urine, use special containers available in pharmacies. These containers prevent contamination of urine sample.
  3. Before collecting urine, the patient must wash their genitalia.
  4. The urine portion collected first after a night’s sleep is used. If necessary, any random urine sample collected during the day may be used.
  5. Urine sample collection during menstruation or 5 to 7 days following cystoscopy is not allowed.
  6. Urine shall be delivered to the laboratory in the morning on the same day, no later than 2 hours after collection. The volume of the sample shall be no less than 50 ml. This examination allows for any portion of urine as the study specimen.
  7. The container holding the biomaterial shall be labeled (special barcode of the patient shall be applied) for inpatients, or shall bear a label stating full name of the patient, their birth date, the name of the department and full name of the physician -- for outpatients.
  8. When collecting a urine sample for microalbuminuria testing, try to prevent any factors that may distort study results. Urine albumin level is increased in cases of an infection, poor compensation of diabetes mellitus, noncompensated arterial hypertension, and is decreased by the administration of non-steroidal anti-inflammatory pharmaceuticals, angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers.
  9. To prevent inaccurate results, it is not recommended to collect urine samples for a common analysis, 24-hour analysis and for the Nechiporenko urine test on the same day!
