The laboratory test for poisoning is a toxicology screening, which typically involves analyzing samples like blood or urine.
Toxicology Screening Explained
Toxicology screening is a crucial diagnostic tool used to identify the presence of drugs, alcohol, and other toxins in the body. This test can help determine the cause of unexplained symptoms, monitor drug use, or confirm poisoning.
Common Sample Types
- Blood: Blood samples provide a snapshot of substances circulating in the bloodstream.
- Urine: Urine samples can detect substances that have been processed and excreted by the body.
- Gastric Contents: In cases of recent ingestion, stomach contents obtained through gastric lavage (stomach pumping) or after vomiting may be analyzed. This is according to information from a reference stating: "Toxicology screening is most often done using a blood or urine sample. However, it may be done soon after the person swallowed the medicine, using stomach contents taken through gastric lavage (stomach pumping) or after vomiting." (02-Jan-2023)
