Intraoperative PTH Monitoring: Importance and Applications in Calcium Regulation
, Intraoperative PTH Monitoring, Parathyroid Gland, Calcium Regulation, Primary Hyperparathyroidism.Parathyroid hormone (PTH) is a crucial biomarker that physicians use to diagnose and manage patients with parathyroid gland-related disorders. The measurement of PTH in serum or plasma is an important tool for the diagnosis and management of primary hyperparathyroidism.Intraoperative PTH monitoring using PTH immunoassay during parathyroidectomy is a widely accepted technique for monitoring the effectiveness of the procedure. The ultimate goal of surgery is to remove all hyperfunctioning parathyroid tissues, leading to a reduction in serum PTH levels. The PTH immunoassay allows for the rapid measurement of serum PTH levels during surgery and is an excellent tool for determining the success of the surgical procedure.PTH is produced by the parathyroid gland, four small glands located in the neck. Parathyroid hormone plays a vital role in calcium regulation, keeping the level of calcium in the blood constant. When the calcium level in the blood decreases, the parathyroid glands produce more PTH, which increases the amount of calcium released from the bones, increases the absorption of calcium from the intestine, and decreases the excretion of calcium through the kidneys.Primary hyperparathyroidism is the most common endocrine disorder, characterized by overactive parathyroid glands, leading to elevated levels of plasma calcium and PTH concentrations. The excessive PTH production and secretion from the parathyroid gland lead to high levels of calcium in the blood, resulting in various medical complications. The most common complication of primary hyperparathyroidism is kidney stones, followed by bone pain and osteoporosis.Parathyroidectomy is the surgical removal of one or more of the parathyroid glands, which is the only cure of primary hyperparathyroidism. Intraoperative PTH monitoring during parathyroidectomy is a valuable tool for verifying the success of surgery. The PTH immunoassay allows for the rapid measurement of serum PTH levels during the surgical procedure, helping surgeons to ensure that all hyperfunctioning parathyroid glands have been removed.To perform intraoperative PTH monitoring, a baseline PTH level is measured before the surgery. After the removal of a suspected hyperfunctioning gland, the PTH level is again measured at 10-15 minutes and 20-30 minutes after the gland removal. If the PTH level drops by 50% or more from the baseline level, it confirms successful removal of the hyperfunctioning gland.PTH immunoassay is a sensitive and specific laboratory method that measures the PTH concentration in serum or plasma. The immunoassay is a rapid and reliable method for measuring serum PTH levels and is used in the diagnosis and management of primary hyperparathyroidism. The availability of PTH immunoassay has revolutionized the intraoperative PTH monitoring, making it an essential tool to ensure the success of parathyroidectomy surgery.Intraoperative PTH monitoring using PTH immunoassay is an essential tool for verifying the success of parathyroidectomy surgery. The PTH immunoassay allows for the rapid measurement of serum PTH levels during surgery, providing clinicians with rapid feedback on the effectiveness of the procedure. Early detection and successful treatment of primary hyperparathyroidism can prevent long-term complications such as bone density loss and osteoporosis.

It has become one of the most commonly used laboratory tests for diagnosing and monitoring a variety of diseases, such as HIV, hepatitis, cancer, autoimmune disorders, and allergies.The principle behind ELISA test is based on the specific binding of an antigen (or antibody) to its complementary antibody (or antigen) immobilized on a solid support, usually a microplate. The sample containing the analyte of interest is added to the plate and allowed to interact with the antigen-antibody complex. Then, a second antibody conjugated with an enzyme, such as horseradish peroxidase (HRP), is added to the plate. This secondary antibody binds to the analyte-antibody complex and forms a sandwich-like structure. After washing away the unbound components, a substrate for the enzyme, such as a colorimetric or chemiluminescent compound, is added to the plate. The enzyme converts the substrate into a detectable signal, which can be measured by a spectrophotometer or a luminometer.The advantage of ELISA test is its high sensitivity and specificity, which means it can detect very low levels of analytes and distinguish between closely related molecules. ELISA test is also relatively easy to perform, requires minimal equipment, and can be adapted to high-throughput screening. However, ELISA test has some limitations, such as its dependence on the quality and specificity of the antibodies used, the possibility of interference from matrix components in the sample, and the potential for false positive or negative results.Immunoassay is a general term that encompasses a variety of methods for detecting and quantifying molecules based on the specific interaction between antigens and antibodies. ELISA test is just one type of immunoassay, which uses enzymes as markers. Other types of immunoassay include radioimmunoassay (RIA), fluorescence immunoassay (FIA), and chemiluminescence immunoassay (CLIA).In conclusion, ELISA test is an important tool in the field of diagnostics and research, and has contributed to the understanding and treatment of numerous diseases.
