The primary function of a central bank is to control the nation's money supply (monetary policy), through active duties such as managing interest rates, setting the reserve requirement, and acting as a lender of last resort to the banking sector during times of bank insolvency or financial crisis.
When crystals are found in the urine it is an indication or a symptom that something is wrong in the urinary system. The urinary system is made up of the kidney, bladder, ureters and urethra. Modification in the diet as well as urine concentration can be a cause of the crystals but there are other causes also.
Amorphous crystals are often identified on the basis of the urine pH. In an acid specimen, urates are reported, in an alkaline specimen, amorphous phosphates are reported. This simplification should be used with care. Amorphous phosphates and triple phosphates are sometimes observed in slightly acid specimens.
