BREATH TESTS Meaning and
Definition
-
Breath tests refer to analytical procedures that are designed to measure the concentration or presence of certain substances in a person's exhaled breath. These tests are often used to evaluate or detect the levels of specific substances, most commonly alcohol or drugs, in a person's body.
When it comes to alcohol testing, breath tests are commonly used for breath alcohol concentration (BAC) analysis. These tests involve the measurement of the ethanol content in a person's breath, which is directly correlated to the alcohol content in their bloodstream. This information is crucial for determining if an individual is legally intoxicated or impaired while operating a vehicle or engaging in other activities that require sobriety.
In addition to alcohol, breath tests can also be used for drug screening. These tests work by detecting and measuring the presence of certain drugs or their metabolites in the breath. This method is particularly useful for identifying recent drug use or determining impairment levels in individuals who may be suspected of driving under the influence of drugs.
Breath tests are non-invasive and offer rapid results, making them convenient and efficient tools for assessing an individual's condition regarding alcohol or drug consumption. However, it is important to note that while breath tests provide initial screening information, confirmatory testing through more accurate methods, such as blood tests, might be necessary for legal or medical purposes.

Etymology of BREATH TESTS
The term "breath tests" combines two words: "breath" and "tests".
The word "breath" traces back to the Old English word "brǣþ", which was derived from the Proto-Germanic root "brēþ-" meaning "smell, exhalation". It has cognates in various Germanic languages, such as Old High German "brādam" and Old Norse "andrǣða". Over time, the word evolved into its current form, "breath", in Middle English.
The word "tests" is derived from the Latin word "testum", which referred to a "piece of earthen pot". In Latin, "testum" developed into "testa" and then into "testis", which meant "witness" or "judge".
