Aspergillus Auto-Toxin (Sterigmatocystin) - IgG

Sample type: Serum
Optimal result: 0 – 0.15 Units

Sterigmatocystin, a related dihydrofuran toxin, is a late metabolite in the aflatoxin pathway and is also produced as a final biosynthetic product by a number of species such as Aspergillus Penicillium, and Bipolaris. STC is a possible human carcinogen (2B) according to IARC classification and showed immunotoxic and immunomodulatory activity, together with mutagenic effects. It might be found in numerous substrates, from foods and feeds to chronically damp building materials and indoor dust.

Due to the structural similarities, aflatoxins and STC share relevant toxic effects, including genotoxicity and carcinogenicity. However, in contrast to aflatoxins, only limited information on occurrence and toxicity of STC is available. Liver and kidneys are the target organs of acute toxicity of STC. However, the acute oral toxicity is relatively low (range between 120 and 166 mg/kg body weight).

Aspergillus Auto-Toxin (Sterigmatocystin) carcinogenic (causes cancer), mutagenic (causes mutations), andteratogenic (causes malformations of the fetus), hepatotoxic (liver); can cause autoimmune diseases.

Sterigmatocystin (STG) is a mycotoxin that is closely related to aflatoxin. STG is produced from several species of mold such as Aspergillus, Penicillium, and Bipolaris. It is considered to be carcinogenic, particularly in the cells of the GI tract and liver. STG has been found in the dust from damp carpets.

It is considered to be carcinogenic, particularly in the cells of the GI tract and liver. STG has been found in the dust from damp carpets. It is also a contaminant of many foods including grains, corn, bread, cheese, spices, coffee beans, soybeans, pistachio nuts, and animal feed. In cases of lung aspergilloma, STG has been found in human tissue specimens. The toxicity of STG affects the liver, kidneys, and immune system. Tumors have been found in the lungs of rodents that were exposed to STG.  Oxidative stress becomes measurably elevated during STG exposure, which causes a depletion of antioxidants such as glutathione, particularly in the liver.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
