If any more or less serious illness without urine can not do. It is a real mirror of the state of the body. So abhor confusion and thoroughly understand, as evidenced by the numbers on the form you received.

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.
