This page is for flow cytometry professionals preparing for the Specialist in Cytometry, SCYM(ASCP), the ASCP Board of Certification credential that replaced the ISAC exam. It collects free practice sets on lab topics such as quality control, sample handling and incident reporting. It also sets out the rules on eligibility, the $310 fee, retakes and score reports.
Numbers in brackets link to the official sources listed under Sources & last verified. Dates that have passed are removed automatically.
According to ASCP Board of Certification (ASCP BOC), which runs the Specialist in Cytometry (SCYM) credential that replaced the ISAC/, “These 4 years of experience must be within the last 8 years and must be documented on this Experience Documentation Form.”[5]
The Specialist in Cytometry credential, SCYM(ASCP), is run by the ASCP Board of Certification (ASCP BOC). It replaced the older ISAC credential. It is meant for people who work in flow cytometry laboratories and want formal recognition of that work.
Delivery. The exam is computer-based. ASCP BOC says its certification examinations are given at approved Pearson testing centers, so you book a seat at a test center rather than sitting it at home.
Eligibility. You need a bachelor's degree plus 4 years of flow cytometry lab experience. The requirement drops to 3 years with a master's degree or another ASCP certification, and to 2 years with a doctorate. The experience must fall within the last 8 years and be documented on the ASCP Experience Documentation Form.
Fee and retakes. The application fee is $310 and is non-refundable. You may sit the exam up to 5 times under one eligibility route, provided you still meet the requirements.
Results. You see a preliminary pass or fail result on screen. The official score report follows within a week. You are not credentialed until that report is available to you, and it shows your certification number and the dates of your 3-year credential cycle.
The content outline, fees and policies can change. Check the SCYM page on ascp.org before you apply. This page is a study aid and does not replace that source.
Prepare for the ISAC - International Society for the Advancement of Cytometry exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: How long must professional records typically be maintained?
Answer: A. According to state and federal regulations, often 7-10 years or longer
Explanation:
The correct answer is that records are kept according to state and federal regulations, often 7-10 years or longer. Retention periods are set by law and by the rules of the organization you work under, so they are not left to local habit.
Keeping records only until a patient is discharged is wrong because the legal and quality-review need for them continues long after discharge. Keeping them for exactly one calendar year is wrong because it is a fixed period that matches no regulation. Keeping them until the file cabinet is full is wrong because storage space is never the basis for a retention rule.
Rule to remember: retention is driven by regulation, and longer periods can apply, for example for minors. Look up the requirement that applies to your own lab and state.
Question: Which of the following scenarios would most likely trigger mandatory external reporting to a state health department laboratory program?
Answer: B. A pattern of systematic reportable disease misclassification affecting multiple patients
Explanation:
The correct answer is a pattern of systematic misclassification of reportable diseases affecting multiple patients. Errors like this can distort public health data, so they trigger an obligation to notify the state health department.
A pipetting error caught internally during QC is wrong because the lab's own control process found and handled it before any result went out. An instrument malfunction corrected quickly is wrong for the same reason: it is an internal quality matter, not a reporting event. A staff member taking unscheduled leave is wrong because it is a staffing issue with no effect on reported results.
Rule to remember: external reporting follows impact on patients and public health, not the mere fact that something went wrong inside the lab.
Question: Which of the following best describes a 'sentinel event' in the context of cytometry laboratory incident reporting?
Answer: B. An unexpected event resulting in death or serious physical harm
Explanation:
The correct answer is an unexpected event resulting in death or serious physical harm. A sentinel event is defined by the severity of its outcome, and it calls for immediate investigation and response.
A minor instrument calibration drift caught during QC is wrong because it was detected by routine controls and caused no serious harm. A reagent lot change requiring new validation is wrong because it is a planned, routine quality step. A software update that temporarily halts workflow is wrong because it causes delay, not serious injury.
Rule to remember: when a question asks about a sentinel event, look for serious harm. Routine QC findings, planned changes and short interruptions do not qualify.
Start with the official SCYM page on ascp.org. Confirm that you meet the eligibility route and read the current content outline. Our practice sets are written by us and are not real exam questions, so use them to find weak spots and not to predict what you will see.
The ISAC credential has been replaced by the Specialist in Cytometry, SCYM(ASCP), which is run by the ASCP Board of Certification. If you want a cytometry credential today, the SCYM is the one to look at. Check ascp.org for the current requirements and application steps.
You need a bachelor's degree and 4 years of flow cytometry lab experience. That drops to 3 years with a master's degree or another ASCP certification, and to 2 years with a doctorate. The experience must be within the last 8 years and documented on the ASCP form.
The application fee is $310 and it is non-refundable. Fees can change, so confirm the amount on the ASCP BOC website before you pay. Because the fee is not returned, check your eligibility route and documentation carefully before you submit.
You may sit the exam up to 5 times under one eligibility route, as long as you continue to meet that route's requirements. If your situation changes, read the ASCP BOC application policies to see how the rule applies to you.
You see a preliminary pass or fail on screen after the exam. The official score report arrives within a week. You are not credentialed until that report is available to you. It lists your certification number and the dates of your 3-year credential cycle.
