Refractometry and urinometry

WebSeveral methods are available for urinary solute concentration determination, such as osmometry (OSM) (reference method) and urine density (UD). UD can be determined by urinometry, refractometry (RF) and reactive strips (RS). In veterinary medicine, RF is the most commonly used method; however, the use of RS to determine UD is increasing in … WebA urine specimen for routine urinalysis would be rejected by the laboratory because: answer choices The specimen had been refrigerated More than 50 mL was in the container The specimen and accompanying requisition did not match The label was placed on the side of the container Question 5 60 seconds Q.
