: Chloroform [Mass concentration] in Serum or Plasma
: This test measures the amount (mass concentration) of chloroform in a sample of serum or plasma, usually to assess exposure to this volatile chemical.
[": The result reflects how much chloroform is present in the liquid portion of your blood at the time of collection."]

: What Is Being Measured
: Chloroform is a volatile solvent that can enter the body through breathing, skin contact, or ingestion. This test measures its mass concentration in serum or plasma, the clear liquid portion of blood. Because chloroform leaves the blood quickly, timing of the sample matters.
: Why the Test May Be Ordered
: A healthcare provider may order this test when someone has known or suspected exposure to chloroform, such as in a workplace, laboratory, or environmental setting. It is not a routine screening test and is generally used to help evaluate a specific exposure concern.
: How the Sample Is Collected
: A blood sample is drawn from a vein, usually in your arm, and collected in a tube appropriate for chemical testing. Proper collection and handling are important because chloroform can evaporate from the sample or be affected by contamination, so tell the collector about any recent chemical exposures.
: What Results May Mean
: A detectable or higher level suggests recent exposure to chloroform. Results must be interpreted by a healthcare provider alongside your symptoms, exposure history, and other tests. A single result does not by itself diagnose poisoning or predict long-term health effects.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
: Chloroform is a central nervous system depressant and can affect the liver and kidneys with significant exposure. Blood measurement is most useful soon after exposure because the chemical is cleared relatively quickly; interpretation depends on the timing of collection, the exposure route, and individual factors, and results should always be reviewed by a qualified healthcare professional.
