What type of container is typically used for collecting CDT samples?

The collection of CDT (carbohydrate-deficient transferrin) samples typically requires non-fixative containers. Non-fixative containers avoid the introduction of any substances that could alter the sample’s composition or stability, which is crucial for accurate laboratory analysis. These containers are specifically designed to prevent chemical interaction with the sample during the collection and handling process, ensuring the integrity of the CDT sample for reliable testing.

Using a non-fixative container is essential because fixatives may change the protein structure or concentration, leading to inaccurate results. Therefore, to maintain the quality of the CDT sample from the moment of collection until analysis, non-fixative containers are the most appropriate choice. This ensures that the laboratory can provide precise and valid results, which are critical for both diagnosis and monitoring of conditions related to alcohol consumption.
