Under ideal situations myoglobin will be filtered and excreted with the urine, but if too much myoglobin is released into the circulation or in case of kidney problems, it can occlude the kidneys' filtration system leading to acute tubular necrosis and acute kidney injury. Other causes of myoglobinuria include: McArdle's disease
The myoglobin is filtered by the kidneys, but is toxic to the renal tubular epithelium and so may cause acute kidney injury. [32] It is not the myoglobin itself that is toxic (it is a protoxin), but the ferrihemate portion that is dissociated from myoglobin in acidic environments (e.g., acidic urine, lysosomes).

Rhabdomyolysis may cause kidney failure by several mechanisms. The most important is the accumulation of myoglobin in the kidney tubules. [10] [11] [13] Normally, the blood protein haptoglobin binds circulating myoglobin and other heme-containing substances, but in rhabdomyolysis the quantity of myoglobin exceeds the binding capacity of ...
A urine test strip or dipstick is a basic diagnostic tool used to ... The presence of myoglobin in urine gives a positive reaction in the test strip's blood test but ...
Urine typically has a mild odor, but strong or unusual smells can indicate a problem. A strong ammonia scent could suggest dehydration. A foul or unusual smell could be a sign of a urinary tract ...
Exertional rhabdomyolysis, the exercise-induced muscle breakdown that results in muscle pain/soreness, is commonly diagnosed using the urine myoglobin test accompanied by high levels of creatine kinase (CK). Myoglobin is the protein released into the bloodstream when skeletal muscle is broken down. The urine test simply examines whether ...
Some patients who have cloudy urine may have higher levels of protein in their urine, a condition known as proteinuria, says Dr. Ramin. Causes may include relatively harmless symptoms, including ...
If you see foamy urine and you haven’t felt like yourself for a while, check in with your doctor. Treatment often includes steroids or other medications to suppress the immune system. 8.
