What is collection and transport of specimen?

Whenever possible, collect all culture specimens prior to administration of any antimicrobial agents. Specimens for bacterial culture should be transported at room temperature. If transport is delayed the following specimens should be refrigerated: urines (within 30 min), stool (within 1 h), respiratory specimens.

Why do we need to transport the specimen immediately to the laboratory?

Specimens for culture should be transported to the laboratory as promptly as possible for processing. Specimen containers must be transported in such a way as to minimize damage that could result in contamination ofthe specimen or exposure ofpersonnel to blood or other body fluids.

What media is used for specimen transport?

Cotton, plastic, wood-handled, and dacron and other synthetic swabs are all acceptable. Calcium alginate swabs should be avoided. Bacterial transport media are not appropriate for virology.

What is the importance of proper specimen collection transport and preservation of a stool specimen?

It is a foundational principle for any laboratory test procedure that the value of the test is compromised or even negated by using specimens that have not been properly collected, labelled, handled or stored prior to and during the testing process.

What is the purpose of specimen collection?

Introduction. Obtaining a specimen involves the collection of tissue or fluids for laboratory analysis or near-patient testing, and may be the first step in determining a diagnosis and treatment (Dougherty and Lister, 2015).

What are the principles of specimen collection?

Equipment used for the collection of specimens should be clean and dry. No antiseptic should be present in the specimen bottle. As far as possible morning specimens are collected. If a culture specimen is required – use sterile containers, get midstream specimen or catherized specimen in case of urine specimen.

What is the principle of standard specimen?

Actions: Specimens should be always fresh for the laboratory examination. Send the specimens to the laboratory as soon as they are collected. The motility of the organism can be noted only when they are fresh. Principle: Decomposition of specimen.

What is the purpose of adding charcoal to some transport media?

The use of charcoal in transport media neutralizes toxic materials in the specimen or on the swab and facilitates the growth of sensitive bacterial pathogens such as Neisseria gonorrhoeae.

What are the types of specimen collection?

The types of biological samples accepted in most clinical laboratories are: serum samples, virology swab samples, biopsy and necropsy tissue, cerebrospinal fluid, whole blood for PCR, and urine samples. These are collected in specific containers for successful processing in the laboratory.

What are the basic rules for specimen collection?

Specimen collection and processing procedures

  • Avoid patient identification errors.
  • Draw the tubes in the proper sequence.
  • Use proper containers for collection.
  • Mix all tubes ten times by gentle inversion immediately after collection.
  • Do not decant specimens from one type of container into another.

What is the meaning of specimen collection?

Specimen collection is the process of obtaining tissue or fluids for laboratory analysis or near-patient testing.

What are the different types of specimen?

What is a Type specimen?

  • Holotype – a single specimen expressly designated as the name-bearing “type” by the original author of the species.
  • Syntype – one of several specimens in a series of equal rank used to describe the new species where the author has not designated a single holotype.
