What is the first action to take when samples arrive at the cytogenetics lab?

1. Conduct a viability test

2. Prepare stains

3. Log them into the system

4. Initiate culture growth

The correct answer is: Log them into the system

Logging samples into the system is the first step upon their arrival at the cytogenetics lab. This process is crucial as it ensures accurate tracking and identification of samples throughout the testing process. Proper logging strengthens the integrity of the laboratory's chain of custody, maintains patient confidentiality, and enhances overall laboratory organization. It allows the laboratory staff to keep detailed records of each sample, which is vital for tracing back any issues that may arise during subsequent testing phases. Initiating culture growth, conducting a viability test, or preparing stains are important processes that follow the initial logging of samples. However, without properly logging the samples, those subsequent steps cannot be effectively managed or linked to the correct patient or case, potentially leading to errors or misinterpretations in the diagnostic process. Thus, the action of logging samples serves as the foundational step that underpins all further activities in the lab.
