What type of tests are typically performed with samples from a Light Green tube?

The Light Green tube is commonly used for certain types of tests that require plasma or whole blood for analysis. Among the tests typically performed with samples from this tube are STAT electrolytes (often referred to as "lytes"), which are crucial for assessing a patient's electrolyte balance. Additionally, the Light Green tube is also used for hCG tests, which measure the hormone human chorionic gonadotropin, primarily to check for pregnancy or certain disease conditions.

This choice highlights the primary functions of the Light Green tube, which contains a specific additive that enables rapid separation of plasma from cells, making it suitable for these urgent tests that often require immediate results.

In contrast, Blood Bank tests and cross-match tests would typically require different types of collection tubes that prevent contamination and preserve blood integrity. Ammonia tests also have specific collection tube requirements to prevent contamination and degradation of the sample, further distinguishing them from the tests associated with the Light Green tube.
