<unk> , also called microscopic hematuria (both usually abbreviated as MH), is a medical condition in which urine contains small amounts of blood; the blood quantity is too low to change the color of the urine (otherwise, it is known as gross hematuria). While not dangerous in itself, it may be a symptom of kidney disease, such as IgA nephropathy or Sickle cell trait, which should be monitored by a doctor. The American Urological Association (AUA) recommends a definition of microscopic hematuria as three or more red blood cells per high-power microscopic field in urinary sediment from two of three properly collected urinalysis specimens.<unk>  is usually asymptomatic, and there are medical guidelines on how to handle asymptomatic<unk>  (AMH) so as to avoid problems such as overtreatment or misdiagnosis.
