✍️ Sample ISAC Questions & Answers

1. What should a ISAC professional do when they encounter a situation beyond their competence?
Refer to a qualified specialist or seek additional training

Recognizing the limits of ones competence and making appropriate referrals is a fundamental professional responsibility.

2. What is the role of a Laboratory Information System (LIS) in flow cytometry documentation?
It centralizes patient ordering, result entry, and audit trails for traceability

An LIS integrates specimen ordering, result entry, and audit trails into a centralized system that supports traceability and regulatory compliance.

3. What is the minimum information that must be recorded when a flow cytometry reagent (antibody conjugate) is opened for the first time?
Date opened, lot number, expiration date, and initials of the person opening the reagent

Opening records must capture date opened, lot number, expiration date, and operator initials to ensure reagent traceability and compliance with expiration policies.

4. What is the purpose of an account lockout policy in an authentication system?
To disable accounts after a set number of failed login attempts, mitigating brute-force attacks

Account lockout policies temporarily or permanently disable an account after repeated failed authentication attempts, making brute-force and password-spraying attacks impractical.

5. Which document type establishes the specific steps an operator must follow when acquiring a lymphocyte subset panel, ensuring reproducibility?
Standard Operating Procedure (SOP)

A Standard Operating Procedure defines step-by-step instructions for a specific assay, ensuring all operators perform it the same way.

6. In mass cytometry (CyTOF), what replaces fluorescent labels?
Heavy metal isotope tags

Mass cytometry uses antibodies conjugated to heavy metal isotopes detected by time-of-flight mass spectrometry, eliminating spectral overlap limitations.
