Types of Specimen Containers in Phlebotomy

Blood Specimen Containers

When it comes to blood specimens, there are various types of containers that are specifically designed for collecting and storing blood samples. These containers are crucial in ensuring that the blood sample remains stable and uncontaminated during transportation to the laboratory.

1. SST Tubes: These tubes contain a gel separator that separates serum from cells once the blood sample has been centrifuged. This type of tube is commonly used for testing liver function, kidney function, and lipid levels.
2. EDTA Tubes: These tubes contain an Anticoagulant called Ethylenediaminetetraacetic acid (EDTA) that prevents blood from clotting. They are commonly used for testing complete blood counts (CBC) and blood type.
3. Heparin Tubes: These tubes contain Heparin, an Anticoagulant that prevents blood from clotting by inhibiting thrombin. They are commonly used for testing electrolyte levels and coagulation studies.

Urine Specimen Containers

Urine specimens are often collected for various tests including urinalysis, pregnancy tests, drug screening, and culture tests. Different types of specimen containers are used to collect urine samples depending on the type of test being performed.

1. Clean Catch Containers: These containers are used to collect urine samples for routine urinalysis and culture tests. It is important for patients to follow proper instructions for collecting clean catch samples to prevent contamination.
2. 24-Hour Urine Collection Containers: For certain tests that require a 24-hour urine collection, a special container with preservatives may be provided to the patient to collect all urine produced within a 24-hour period.
3. Drug Test Cups: These containers are often used for rapid drug screening tests and can detect multiple drugs in a single sample of urine.

Other Specimen Containers

Aside from blood and urine specimens, there are also other types of specimens that may require specific containers for collection and transportation to the laboratory.

1. Stool Specimen Containers: These containers are used to collect stool samples for testing for gastrointestinal infections, parasites, and blood in the stool.
2. Swab Specimen Containers: These containers are used to collect samples from the throat, nose, wounds, or other areas for testing for bacterial or viral infections.
3. Sputum Specimen Containers: These containers are used to collect samples of phlegm coughed up from the respiratory tract for testing for respiratory infections.

Importance of Using the Right Specimen Containers

Using the right type of Specimen Container is essential for accurate testing and diagnosis. Improper containers or contamination during specimen collection can lead to inaccurate results, potentially affecting patient care and treatment decisions.

Here are some reasons why using the right specimen containers is crucial:

1. Prevention of Contamination: Each type of Specimen Container is designed to prevent contamination and ensure the integrity of the sample. Using the wrong container can introduce contaminants that may affect Test Results.
2. Stability of Sample: Specimen containers are designed to maintain the stability of the sample during transportation to the laboratory. Improper containers may compromise the integrity of the sample, leading to inaccurate results.
3. Accurate Diagnosis: Accurate testing and diagnosis rely on the quality of the specimen collected. Using the right type of Specimen Container can help ensure that the sample is suitable for testing, leading to more reliable results.

Conclusion

Having a good understanding of the different types of specimen containers used in phlebotomy is crucial for healthcare professionals working in urgent care clinics. By using the right type of container for each specimen, Healthcare Providers can improve the efficiency and quality of patient care by ensuring accurate testing and diagnosis.
