Which tube is utilized for molecular PCR and bDNA testing?

The white tube is designed specifically for molecular testing techniques such as polymerase chain reaction (PCR) and branched DNA (bDNA) testing. This specialized tube contains additives that help stabilize the nucleic acids by preventing degradation and ensuring the integrity of the sample during transportation and storage.

Molecular tests require high-quality samples to ensure accurate results, and the white tube is crafted to support the needs of such assays by providing the appropriate environment for preserving nucleic acids. This makes it ideal for further analysis in laboratories focused on genetic testing or infectious disease detection, where the integrity of the sample is critical.

The other types of tubes listed each serve different purposes: for instance, the gray tube typically contains additives for glucose testing to prevent glycolysis, the light blue tube is used for coagulation studies, and the gold tube is often utilized for serum testing but not specifically targeted for molecular practices. Thus, the specification of the white tube for molecular PCR and bDNA testing highlights its essential role in handling and analyzing nucleic acids effectively.
