What is the term for elevated ammonia levels?

Hyperammonemia is a metabolic condition characterized by raised levels of ammonia, a nitrogen-containing compound. Ammonia is a potent neurotoxin. Hyperammonemia most commonly presents with neurological signs and symptoms that may be acute or chronic, depending on the underlying abnormality.

What is the name of the condition where ammonia is elevated?

Hyperammonemia - StatPearls - NCBI Bookshelf. Hyperammonemia is a metabolic condition characterized by the raised levels of ammonia, a nitrogen-containing compound. Normal levels of ammonia in the body vary according to age. Hyperammonemia can result from various congenital and acquired conditions in which it may be the principal toxin.

Why do premature infants have transient hyperammonemia?

Transient hyperammonemia of infancy is possibly due to the slow maturation of the urea cycle function seen in premature infants. It usually presents with signs and symptoms of hypoxic-ischemic encephalopathy and intracranial hypertension within the first 24 to 48 hours of life. Severe perinatal asphyxia or neonatal HSV infection may also result in elevated ammonia levels.

What is the disease that causes hyperammonemia in children?

An acquired disease-causing hyperammonemia in children is Reye syndrome, a childhood disorder that occurs most commonly after influenza or varicella infection and ingestion of aspirin. Hyperammonemia is coupled with elevated liver enzymes and lactic acidosis. Hepatomegaly is usually seen on examination. Liver Disease

How many live births are there in the United States with hyperammonemia?

A gross estimate on the incidence of urea cycle disorders is 1 in 250,000 live births in the United States and 1 in 440,000 live births internationally. [11] Pathophysiology.

Where does ammonia come from?

Normally, ammonia is produced in the colon and small intestine from where it is transported to the liver to be converted to urea via the urea cycle.

What are the causes of hyperammonemia?

Other enzymatic defects causing hyperammonemia are associated with additional metabolic abnormalities. Ketosis and acidosis are associated with organic acidemias such as isovaleric acidemia. Elevated pyruvate and lactate levels in congenital lactic acidosis and severe hypoglycemia in acyl CoA dehydrogenase deficiency are seen along with hyperammonemia.

Why is my ammonia level high?

In infants, high ammonia levels may be a sign of a genetic disease of the urea cycle or a condition called hemolytic disease of the newborn. This disorder happens when a mother develops antibodies to her baby's blood cells.

What happens during an ammonia levels test?

A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

Why do I need an ammonia levels test?

You may need this test if you have liver disease and are showing symptoms of a brain disorder. Symptoms include:

What happens if you don't get ammonia?

Urea is passed through the body in urine. If your body can't process or eliminate ammonia, it builds up in the bloodstream. High ammonia levels in the blood can lead to serious health problems, including brain damage, coma, and even death. High ammonia levels in the blood are most often caused by liver disease.

Is there anything else I need to know about an ammonia levels test?

Some health care providers think blood from an artery may provide more useful information about ammonia than blood from a vein. To get a sample of arterial blood, a provider will insert a syringe into the artery in your wrist, elbow crease, or groin area. This method of testing is not used very often.

Clinical Significance

Ammonia, Plasma - Ammonia is one of the by-products of protein metabolism. Elevated blood ammonia levels have been associated with severe liver dysfunction such as hepatic encephalopathy, coma resulting from cirrhosis, severe hepatitis, Reye's syndrome and drug hepatotoxicity.

Collection Instructions

Collect blood from stasis-free vein of patient (e.g., no tourniquet). Patient should not clench fist during collection, as muscular exertion often increases venous ammonia levels. Patient should avoid smoking prior to phlebotomy since smoking increases plasma ammonia levels. Tubes should be filled completely and kept tightly stoppered at all times.

What is the code for hyperammonemia?

Code 270.6 is hyperammonemia (congenital), and we can only code 'congenital' if physician documents it as so. I think in this case-I would go with 790.6 "Abnormal Blood Chemistry". Thanks!

Yes , 270.6. [elevated amounts of ammonia in the blood (hyperammonemia)].#N#When adults experience mental changes, disorientation, sleepiness, or lapse into a coma, an ammonia level may be ordered to help evaluate the cause of the change in consciousness, it helps to diagnose the cause of a coma of unknown origin or to help support the diagnosis of Reye’s syndrome or hepatic encephalopathy caused by various liver diseases. An ammonia level may also be ordered to help detect and evaluate the severity of a urea cycle defect.#N#In patients with stable liver disease, an ammonia level may be ordered, along with other liver function tests, when a patient suddenly “takes a turn for the worse” and becomes more acutely ill.
