What tests are typically performed on samples collected in lavender tubes?

• A. OGTT, Lactic Acid, ETOH
• B. CBC, Platelets, Hemoglobin
• C. Heavy Metal Toxicology, Lead Poisoning
• D. Glucose, Cholesterol

Answer: (B)

Lavender tubes are used to collect samples for tests that require an anticoagulant, commonly EDTA, which helps in preserving the cellular components of the blood. The specific tests typically performed on samples collected in lavender tubes include a Complete Blood Count (CBC), which measures various components of the blood including red blood cells, white blood cells, and platelets.

Additionally, the analysis of platelets and hemoglobin levels is also conducted using samples from lavender tubes because these tests rely on the ability to count and analyze cellular elements without the interference of clotting. The lavender tube ensures that the sample maintains its integrity for these types of analyses, which are essential for diagnosing a variety of health conditions. This demonstrates the critical role of anticoagulants in laboratory testing and the specific applications of lavender tubes in routine hematological examinations.
