What are the methods of 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 collection and transport of specimen?
Specimens may be transported through the pneumatic tube system if approved by Pneumatic Tube Administration. This includes blood culture bottles (if placed in plastic carrier), Vacutainer® tubes and swabs. Specimens should be in tightly sealed, leak proof containers and transported in sealable, leak-proof plastic bags.
What is specimen transportation?
Specimen Transport. Upon labeling the specimens at the patient’s bedside, the specimens should be placed in a biohazard bag, tube rack, or any other transport carrier required by the testing facility. Transport to the laboratory should be done as soon as possible after collection.
What is the best way to transport specimen collected for laboratory analysis?
Specimens should be placed in tightly sealed containers; the containers should be free of any external spillage, and the specimens should be transported in plastic biohazard ziplock bags. 2. Collect the specimen from the actual site of infection, avoiding contamination from adjacent tissues or secretions.
What is the purpose of specimen collection?
Specimen collection is a common component of routine checkups for your health. It goes hand-in-hand with lab tests, allowing medical professionals to obtain tissue or fluids to look for any changes in your health. In addition, they help physicians diagnose medical conditions, plan treatments, and monitor diseases.
Why is proper specimen collection important?
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 are the types of sample transportation?
External samples are transported in a variety of ways, e.g. by car , in boxes , using drones , , or even by planes and trains. If the samples are properly protected from temperature deviation and agitation, none of these transportation forms should affect the samples significantly .
What is the importance of proper specimen collection and transport?
What is the most common method of obtaining a blood specimen?
Blood Collection Methods: Venipuncture is the most common method of obtaining a diagnostic blood specimen. Use of the evacuated blood collection system is preferable because it allows the blood to pass directly from the vein into the evacuated tube eliminating the need for specimen transfer.
What are 4 different types of specimens?
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 is the best way to collect and transport specimen types?
1 Deliver all specimens to the laboratory as soon as possible after collection. 2 Blood: Media and instructions available upon request from the Microbiology Lab. 3 Sputum: Collect an early morning specimen on three consecutive days. 4 See Bacterial culture for collection and transport of all other specimen types.
How long does it take to transport a specimen to microbiology?
If cultures are desired, Microbiology must receive the specimen first to ensure the culturing of a sterile specimen. Transport time 15 minutes. Do not refrigerate CSF for bacterial culture. If adequate volume is obtained, orders are placed per tube as follows: Tube # Orders #1 – Chemistry/Immunology Protein (LAB118) and Glucose (LAB611)
How do you transport tissue to a microbiology lab?
A sterile container(37777) may be used for tissue if transported to the microbiology lab immediately (add drops of sterile saline to keep small pieces of tissue moist). Copan Liquid Amies Elution Swab(ESwab) (74541) – swab specimens are suboptimal, but will be accepted if no other sample can be obtained.
How should specimen collection and preservation be performed?
Use the container/tube indicated in the test requirements for appropriate specimen preservation. Follow patient instructions prior to specimen collection. Carefully tighten specimen container lids to avoid leakage and/or potential contamination of specimens. Maintain the specimen at the temperature indicated in the test requirements.
