Atomic Absorption Spectroscopy: Interference

Atomic Absorption Spectroscopy: Interference

Interference leads to systematic error in atomic absorption (AA) measurements by enhancing or diminishing the analytical signal or the background. These interferences can be grouped into three main categories: spectral interference, chemical interference, and physical interference.
Spectral interference occurs when signals from other elements or molecules overlap with the analyte signal, falsely elevating or masking the analyte's absorbance. This interference can be corrected using Zeeman,...

Synthesis and Regulation of Thyroid Hormones

Synthesis and Regulation of Thyroid Hormones

Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...

Hybridoma Technology

Hybridoma Technology

Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Hyperthyroidism II: Pathophysiology

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...

Area of Science:

Endocrinology
Clinical Chemistry
Laboratory Medicine

Background:

Immunoassays are standard for thyroid hormone measurement.
Assay interference is a recognized clinical challenge.
Accurate thyroid hormone levels are crucial for diagnosis and treatment.

Observation:

A patient undergoing treatment for Graves' disease experienced assay interference.
Thyroid function tests, including free thyroxine (free T4), free triiodothyronine (free T3), and thyroid-stimulating hormone (TSH), were affected.
Interference occurred during the course of medical management.

Findings:

The patient's thyroid function measurements showed significant interference.
This interference potentially impacted the interpretation of her thyroid hormone status.
The specific cause and extent of interference require further investigation.

Implications:

Assay interference can lead to misdiagnosis and inappropriate treatment.
Clinicians must be aware of potential interferences in immunoassays.
Careful interpretation of thyroid function tests, especially in complex cases like Graves' disease, is essential.
