Urinalysis appointed as general results are suspect: overt pathology like no, but white blood cells and red blood cells slightly increased. Need to clarify the urine from the "mid-stream": jar substituted after the start of urination, and clean up is complete. Of this amount, the lab will take 1 ml and count the number of red blood cells (normal - no more than 1000), leukocytes (less than 2000) and cylinders (less than 20). If one or more parameters are elevated, a pathology.
On analysis resort, if there is a suspicion of renal failure or kidney inflammation. Urine was collected for 6 days in the jar: one for urine released for every 4 hours. In the laboratory, they determine the number and proportion. Complex calculations, but it is important that the volume of urine passed during the day, was more than a night, and that the proportion of all batches ranged in a certain way.
Here are the most common signals of a fault:1010-1012. The density of urine equal to the density of blood plasma (isosthenuria). This can happen if the patient received diuretics or has non-acute pyelonephritis or renal failure.
1002-1008. Urine density less than the density of blood plasma (hyposthenuria). There are signs of severe pyelonephritis.
More than 1025. Chances are dramatically thickened blood - it happens with dehydration, and children - with urate diathesis.
