Which statement correctly identifies Light Green lab usage?

Light green tubes, often referred to as "stat" tubes, are primarily used for chemistry testing. They contain lithium heparin, which acts as an anticoagulant, allowing for the rapid separation of plasma from blood cells. This is particularly important in situations where quick results are required, such as emergency or outpatient settings where immediate analysis is essential.

These tubes are advantageous for a wide range of chemistry tests because they yield plasma that can be used directly in various assays without needing to wait for the blood to clot, which is typically the case for other types of tubes. This makes them a go-to choice for many clinical chemistry laboratories.

In contrast, other laboratory departments such as hematology, blood bank, and microbiology utilize different types of tubes and anticoagulants specifically designed for their needs, which is why light green is not suitable for those applications.
