Interleukin-6 is involved in inflammation and infection responses and also in the regulation of metabolic, regenerative, and neural processes.
Optimal range: 0 - 13.87 pg/mL
Interleukin 8 (IL-8) is a promising marker for many clinical conditions and currently being applied by various subspecialties of medicine either for the purpose of rapid diagnosis or as a predictor of prognosis. Nevertheless, IL-8 level increased as a result of many inflammatory conditions, so careful interpretation of IL-8 level is required to make correlation with desired clinical condition's diagnosis or prognosis.

IDL Cholesterol is a plasma lipoprotein. Cholesterol and triglycerides are insoluble in water and therefore these lipids must be transported in association with proteins. Lipoproteins are complex particles with a central core containing cholesterol esters and triglycerides surrounded by free cholesterol, phospholipids, and apolipoproteins, which facilitate lipoprotein formation and function.

Reference range: Normal Pattern, Abnormal Pattern
In a Protein Electrophoresis test, part of panels like Total Protein and Protein Electrophoresis, 24 Hour Urine, the "pattern" refers to the arrangement and distribution of protein fractions (such as albumin, alpha-1, alpha-2, beta, and gamma globulins) as revealed in the test results. This pattern, which is identified through the separation of proteins based on size and electrical charge, shows the different protein groups and their relative proportions. A normal pattern typically has albumin as the most abundant protein, followed by various globulins. Abnormalities in this pattern can indicate medical conditions such as liver disease, immune disorders, or kidney issues. The pattern is crucial for diagnosing and monitoring these conditions, providing insight into the body's protein composition and any deviations from normal levels.

The Intestinal Fraction on Labcorp's Alkaline Phosphatase (ALP) Isoenzyme Panel represents the portion of alkaline phosphatase derived from the intestines. Elevated levels of the intestinal fraction may be observed after meals, especially in individuals with blood types B or O who are secretors, as they tend to have higher levels of intestinal ALP following food intake. This isoenzyme is measured to help determine the source of elevated ALP levels and to assess gastrointestinal health. By differentiating the intestinal fraction from other sources of ALP, such as the liver or bone, healthcare providers can better understand the cause of elevated enzyme levels and investigate potential gastrointestinal disorders or other related conditions. The ALP isoenzyme panel's precise measurement of this fraction can guide clinicians in diagnosing conditions related to the intestinal system.
Optimal range: 1 - 24 %
Intestinal isoenzymes of alkaline phosphatase are biomarkers that indicate the presence of specific forms of the alkaline phosphatase enzyme within the intestine. This biomarker is significant in assessing the health and function of the intestinal system, as alkaline phosphatase is involved in various physiological processes, including the absorption of nutrients and the maintenance of gut health.

Intrinsic factor is a glycoprotein produced by the parietal cells of the stomach. It is necessary for the absorption of vitamin B12 within distal ileum.
Clinical Significance:
Autoantibodies against Intrinsic Factor are considered highly specific to patients with Pernicious Anemia. Intrinsic Factor antibodies are rarely found in the absence of Pernicious Anemia. Less commonly, Intrinsic Factor antibodies may also be found in patients with Graves’ disease and in relatives of patients with Pernicious Anemia.
Optimal range: 0 - 1.1 AU/mL
Intrinsic factor antibodies are proteins produced by the immune system that are associated with pernicious anemia. This test detects intrinsic factor antibody (IF antibody) circulating in blood.
Reference range: Negative, Positive
Intrinsic factor is a protein that is produced by the parietal cells of the stomach. It binds to vitamin B12, thereby allowing absorption of the vitamin by intestinal cells. In pernicious anemia, an autoimmune disorder, autoantibodies are formed against intrinsic factor leading to its deficiency. The lack of intrinsic factor then causes malabsorption of vitamin B12 and subsequent anemia. Autoantibodies can also be formed directly against the parietal cells which similarly leads to inadequate intrinsic factor activity and vitamin B12 deficiency.
Reference range: Not Detected, Detected
Iodamoeba buetschlii is considered nonpathogenic or commensal. Infection occurs via fecal-oral route, and indicates increased risk of
exposure to potential pathogens.
Optimal range: 15 - 160 ug/L
Iodine is an essential mineral that plays a crucial role in thyroid function. The thyroid gland uses iodine to produce thyroid hormones, which are responsible for controlling growth, repairing damaged cells, and supporting a healthy metabolism.

Monitor exposure to iodine; evaluate for iodine deficiency disorders (IDDs), excessive iodine intake, or iodine in the workplace
Iodine is an essential element for thyroid hormone production. The Iodine 24 Hour Urine Test measures the amount of iodine excreted from the body. It monitors a person’s exposure to iodine and evaluates for iodine deficiency disorders, excessive iodine intake or iodine in the workplace.
Because levels of substances like iodine can fluctuate throughout the day, evaluating a urine collection over 24 hours can provide a more accurate evaluation than a urine test which only looks at a single collection.
Urinary Iodine levels can help determine if a person is getting healthy amounts of iodine from the food they eat. Unusually high or low levels of iodine can lead to a number of disorders such as hyperthyroidism or hypothyroidism.
This test is usually ordered when someone has had irregular results from thyroid tests such as TSH, T3 and T4. Pregnant and nursing women are often tested for iodine because deficiency can have adverse effects on pregnancy and cause developmental difficulties in infants.
Optimal range: 34 - 523 mcg/L
Measurement of urinary iodine excretion provides the best index of dietary iodine intake.
Optimal range: 40 - 92 mcg/L
