Phlebotomy

A certification course focused on blood collection and specimen handling techniques.

Advanced Topics

Specimen Handling and Processing

The Importance of Specimen Integrity

Blood specimens must be handled with care to avoid hemolysis (breaking of red blood cells), contamination, or clotting.

Proper Labeling

Every specimen tube must be labeled with the patient's name, date, time, and test information to prevent mix-ups.

Transport and Storage

Some specimens need refrigeration, while others must be kept at room temperature. Always follow laboratory protocols for transporting and storing samples.

Processing Techniques

Blood may need to be centrifuged to separate plasma or serum. Incorrect handling can affect test results and patient care.

Examples

  • A labeled sample is placed in a biohazard bag for safe transport to the lab.

  • A blood tube is spun in a centrifuge to separate the plasma.

In a Nutshell

Correct handling and processing ensures accurate test results and patient safety.

Key Terms

Hemolysis
Destruction of red blood cells, which can alter test results.
Centrifuge
A machine that spins samples to separate components by density.
