Alpha-Ketoisocaproate is a B-Complex Vitamin Marker (Leucine catabolism).

Vitamins are compounds that your body needs to be healthy. Vitamins are “essential” for proper function, which means that they are not made inside your body and must be consumed in the diet. The B-complex vitamins are necessary for many enzymes in your body to function properly.

Many B vitamins are used as co-factors in the breakdown of amino acids. A deficiency of any of these B vitamins may lead to a block in one or more of these pathways resulting in elevations of the markers.
Vitamins B1 (thiamin), B3 (niacin), and B5 (pantothenic acid) are necessary for energy pathways of all of the cells in your body. As your food is broken down, specific compounds are formed at steps that require B vitamin assistance. Alpha-Ketoisocaproate is one some these compounds. The production of this metabolite requires vitamins B1, B3, B5 and lipoic acid.

Function:

Myosin, the major contractile protein, converts chemical energy into mechanical force through hydrolysis of ATP. a-Myosin is almost exclusively expressed in cardiac tissue.

Antibodies Appear:

- Autoimmune Myocarditis [3]

- Dilated Cardiomyopathy [3]

- Myasthenia Gravis [5]

Alpha-Pregnanediol in men's urine is a significant metabolite of progesterone, and its levels can provide valuable insights into hormonal balance and potential health concerns related to progesterone and androgen metabolism.

Alpha-Pregnanediol, a key biomarker in the FU Female FMV Urine Comprehensive Hormone panel, is a metabolite of progesterone, an essential hormone in female reproductive health. Scientifically, alpha-pregnanediol is a progestogen, a substance that plays a crucial role in the menstrual cycle, pregnancy, and embryogenesis. In the context of the urine hormone panel, the measurement of alpha-pregnanediol provides vital insights into the body's progesterone levels, as it is a direct byproduct of progesterone metabolism.

Alpha-Pregnanediol and Beta-Pregnanediol are metabolites of progesterone, and they are used as surrogate markers because they are the most abundant metabolites. The ratio between these two metabolites can provide insights into the relative activity of specific steroidogenic enzymes or pathways involved in progesterone metabolism.

Naturally occurring vitamin E exists in eight chemical forms (alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol) that have varying levels of biological activity.

Alpha- (or α-) tocopherol is the only form that is recognized to meet human requirements. Alpha-tocopherol (body’s main form of vitamin E) functions as an antioxidant, regulates cell signaling, influences immune function and inhibits coagulation.

Alternaria alternata is one of the most common fungi associated with asthma.

Alternaria alternata (M6) IgE is a blood test that measures IgE antibodies specific to Alternaria alternata — a common outdoor mold strongly associated with allergic asthma and rhinitis. A result below 0.10 kU/L indicates no detectable sensitization. Higher results reflect increasing degrees of immune sensitization to this mold, ranging from mild (0.10–0.35 kU/L) to very high (above 17.5 kU/L). Sensitization does not always equal symptoms — clinical context, exposure history, and symptom severity determine clinical relevance.

Alternaria alternata mold IgE is a specific marker included in allergy panels that helps identify if an individual has an allergic sensitivity to a common type of fungus known as Alternaria alternata. This mold is widely found in the environment, thriving outdoors in soil, plants, and rotting vegetation, and can also make its way indoors through open doors, windows, and ventilation systems. People who are sensitive to this mold may experience allergic reactions when they inhale its spores, leading to symptoms such as sneezing, runny nose, itchy eyes, and asthma exacerbations.
