Introduction
Medical laboratory testing plays a critical role in diagnosing and treating patients in the United States. Blood collection is a common procedure in medical labs, and the type of tube used for collecting blood can impact the accuracy and reliability of Test Results. In this article, we will discuss the different types of tubes used for blood collection in a medical lab setting in the United States.
Types of Tubes
1. Serum Tubes
Serum tubes are used for collecting blood samples for chemistry tests that require serum as the specimen. These tubes typically contain a Clot Activator and Separator Gel that helps separate the serum from the blood cells after the sample has been centrifuged. The most common serum tube color is red, but gold and tiger-topped tubes may also be used for specific tests.
2. Plasma Tubes
Plasma tubes are used for collecting blood samples for tests that require plasma as the specimen. These tubes contain anticoagulants such as EDTA, citrate, or Heparin to prevent the blood from clotting. The most common plasma tube colors are purple (EDTA), light blue (citrate), and green (Heparin).
3. Anticoagulant Tubes
Anticoagulant tubes are used for collecting blood samples for tests that require whole blood or specific types of blood cells. These tubes contain additives that prevent the blood from clotting and preserve the integrity of the sample. Common Anticoagulant tube colors include lavender (EDTA), light blue (citrate), green (Heparin), and gray (oxalate/fluoride).
4. Pediatric Tubes
Pediatric tubes are smaller in size and are used for collecting blood samples from infants and young children. These tubes typically contain less volume of additives to account for the smaller blood sample size. Pediatric tubes may come in various colors depending on the additives included in the tube.
5. Coagulation Tubes
Coagulation tubes are used for collecting blood samples for coagulation tests that assess a patient's clotting ability. These tubes contain Sodium Citrate as an Anticoagulant and are usually light blue in color. Coagulation tubes are essential for monitoring patients on Anticoagulant therapy or diagnosing Clotting Disorders.
6. Microbiology Tubes
Microbiology tubes are used for collecting blood samples for microbiological culture tests to detect and identify infectious pathogens. These tubes typically do not contain any additives to avoid interfering with the growth of microorganisms. Microbiology tubes may come in various colors depending on the specific culture media used.
Conclusion
Understanding the different types of tubes used for blood collection in a medical lab is essential for ensuring accurate and reliable Test Results. Each type of tube serves a specific purpose and contains different additives to preserve blood samples for various types of testing. Proper knowledge of the tubes used for blood collection can help healthcare professionals in the United States make informed decisions about patient diagnosis and treatment.
