Toxicology Testing[edit]

Toxicology testing, also known as toxicity testing, is the scientific analysis of biological specimens to detect the presence of toxins and drugs. This process is crucial in various fields such as medicine, forensic science, and environmental science.

Purpose of Toxicology Testing[edit]

Toxicology testing serves multiple purposes, including:

Medical Diagnosis: To determine the cause of poisoning or overdose in patients.
Forensic Analysis: To assist in criminal investigations by identifying substances in biological samples from crime scenes.
Workplace Safety: To ensure employees are not exposed to harmful levels of chemicals or drugs.
Environmental Monitoring: To assess the impact of pollutants on ecosystems.

Types of Toxicology Tests[edit]

There are several types of toxicology tests, each designed for specific applications:

Urine Tests: Commonly used for drug screening in workplaces and sports.
Blood Tests: Provide a more accurate measure of the concentration of toxins in the body.
Hair Tests: Can detect drug use over a longer period.
Saliva Tests: Used for quick screening, especially in roadside testing.

Toxicology Testing Methods[edit]

Toxicology testing employs various methods to detect and quantify substances:

Immunoassays: Use antibodies to detect specific drugs or toxins.
Gas Chromatography-Mass Spectrometry (GC-MS): A highly sensitive method for identifying and quantifying compounds.
High-Performance Liquid Chromatography (HPLC): Used for separating and analyzing compounds in a mixture.
Spectrophotometry: Measures the amount of light absorbed by a sample to determine the concentration of a substance.

Challenges in Toxicology Testing[edit]

Toxicology testing faces several challenges, including:

Complexity of Samples: Biological samples can contain a wide variety of substances that may interfere with testing.
Sensitivity and Specificity: Tests must be sensitive enough to detect low levels of toxins but specific enough to avoid false positives.
Emerging Substances: New drugs and chemicals are constantly being developed, requiring ongoing updates to testing protocols.

-== Origin and Course ==
+== Purpose of Toxicology Testing ==
-The thoracoacromial artery arises from the second part of the axillary artery. It passes forward, underneath the [[pectoralis minor]], and divides into several branches. These branches include the pectoral, acromial, clavicular, and deltoid branches.
+Toxicology testing serves multiple purposes, including:
-== Branches ==
+* '''Medical Diagnosis''': To determine the cause of [[poisoning]] or [[overdose]] in patients.
-The thoracoacromial artery gives off several branches, which are named according to the areas they supply:
+* '''Forensic Analysis''': To assist in [[criminal investigations]] by identifying substances in [[biological samples]] from crime scenes.
+* '''Workplace Safety''': To ensure employees are not exposed to harmful levels of [[chemicals]] or [[drugs]].
+* '''Environmental Monitoring''': To assess the impact of [[pollutants]] on [[ecosystems]].
-* '''Pectoral branch''': This branch supplies the [[pectoralis major]] and [[pectoralis minor]] muscles.
+== Types of Toxicology Tests ==
-* '''Acromial branch''': This branch supplies the [[acromion]], a part of the [[scapula]] that forms the highest point of the shoulder.
+There are several types of toxicology tests, each designed for specific applications:
-* '''Clavicular branch''': This branch supplies the [[clavicle]], also known as the collarbone.
-* '''Deltoid branch''': This branch supplies the [[deltoid muscle]], a large, triangular muscle covering the joint of the shoulder.
-== Clinical Significance ==
+* '''Urine Tests''': Commonly used for drug screening in workplaces and sports.
-The thoracoacromial artery is an important artery in the upper body, supplying blood to several major muscles and bones. Damage to this artery can lead to significant blood loss and potentially life-threatening complications. It is also a key landmark in surgical procedures involving the shoulder and upper chest.
+* '''Blood Tests''': Provide a more accurate measure of the concentration of toxins in the body.
+* '''Hair Tests''': Can detect drug use over a longer period.
+* '''Saliva Tests''': Used for quick screening, especially in roadside testing.
