Branched Chain Amino Acids (Isoleucine, Leucine, Valine) are the three branched chain amino acids (BCAAs). Branched chain amino acids (BCAA) are essential amino acids and must be obtained from the diet (mainly meat, grains, and dairy).

Isoleucine is one of the three branched-chain amino acids (BCAAs) alongside both leucine and valine.

Isoleucine is a common component of proteins, peptides and hormones. Leucine is catabolized as a source of carbon for energy production during exercise in skeletal muscle.

Branched-Chain Amino Acids (BCAAs) are required for protein synthesis and are metabolized outside hepatic tissues, unlike most other essential amino acids. They are converted to branched-chain keto acids which require B-complex vitamins. BCAAs have been associated with obesity, weight loss, insulin resistance, and nonalcoholic fatty liver disease (NAFLD). 

BCAA’s are nitrogen donors, facilitate glucose uptake by liver and skeletal muscle, and enhance glycogen synthesis.

- BMI was positively associated with urine 2-hydroxyisobutyrate, isoleucine, valine, tryptophan, and tyrosine.

- Elevated urine levels were associated with higher colorectal cancer.

Volatile substances in the blood include ethanol, methanol, isopropanol, and acetone. Acetone is generally elevated in metabolic conditions such as diabetic ketoacidosis. Methanol and isopropanol are highly toxic and result from exogenous ingestion.

The presence of isopropanol indicates exposure which may result in intoxication and CNS depression. Ingestion of isopropanol can be fatal if patients do not receive immediate medical treatment.

Isosatratoxin F is another trichothecene produced by Stachybotrys chartarum. Several animal studies have shown that isosatratoxin F can cause nasal and pulmonary toxicity when administered intranasally or intratracheally. They showed that pulmonary alveolus cells were injured following intratracheal instillation of isosatratoxin F with marked changes in surfactant synthesis and secretion.

Isovalerylglycine is a breakdown product of leucine. 

Isovalerylglycine is produced from leucine catabolism. It is further metabolized via isovaleryl-CoA dehydrogenase. This enzyme requires vitamin B2 as a cofactor.

Japanese encephalitis virus (JEV) is a flavivirus related to dengue, yellow fever and West Nile viruses, and is spread by mosquitoes (especially Culex tritaeniorhynchus).

JEV is the main cause of viral encephalitis in many countries of Asia with an estimated 100 000 clinical cases every year.

Although symptomatic Japanese encephalitis (JE) is rare, the case-fatality rate among those with encephalitis can be as high as 30%. Permanent neurologic, cognitive and behavioural sequelae occur in 30–50% of those with encephalitis.

This test measures the amount of antibodies to anti-Jo-1 in blood. It is used to help diagnose and manage muscle diseases that affects the immune system such as polymyositis (a type of chronic inflammation of the muscles) associated with autoimmune disease.

Presence of Jo-1 (antihistidyl transfer RNA [t-RNA] synthetase) antibody is associated with polymyositis and may also be seen in patients with dermatomyositis.

Polymyositis is one of a group of rare diseases called the inflammatory myopathies that involve chronic (long-standing) muscle inflammation and weakness, and in some cases, pain. Myopathy is a general term used to describe a number of conditions affecting the muscles. All myopathies can cause muscle weakness.

Jo-1 antibody is also associated with pulmonary involvement (interstitial lung disease), Raynaud phenomenon, arthritis, and mechanic's hands (implicated in antisynthetase syndrome).

Detect possible allergic responses to various substances in the environment such as animals, antibiotics, foods, grasses, house dust, mites, insects, insulin, molds, smuts, trees, and weeds; evaluate hay fever, asthma, atopic eczema, and respiratory allergy.
