Frequently Asked Questions

How many questions are on the ASCP C exam?

The ASCP C exam consists of 100 multiple-choice questions administered over a 2.5-hour testing period at Pearson VUE test centers.

What score do I need to pass the ASCP C exam?

ASCP reports exam scores on a 100-999 scale. The minimum passing score for the C exam is 400.

What topics are tested on the ASCP C exam?

The C exam covers clinical chemistry and electrolytes, enzymes and proteins, lipids, endocrinology, therapeutic drug monitoring, toxicology, point-of-care testing, and analytical instrumentation.

How much does the ASCP C exam cost in 2026?

The current ASCP BOC C application fee is $240 (non-refundable). This fee covers the exam application and one testing attempt.

What is the difference between C(ASCP) and MLS(ASCP)?

C(ASCP) is a specialty credential focused solely on clinical chemistry, while MLS(ASCP) is a generalist certification covering all major laboratory disciplines. The C credential demonstrates deeper chemistry expertise.

How should I study for the ASCP C exam?

Prioritize clinical chemistry calculations (anion gap, osmolality, creatinine clearance), enzyme and electrolyte interpretation, and instrumentation principles. Practice correlating abnormal results with clinical conditions.

What career opportunities does the C(ASCP) credential provide?

C(ASCP)-certified technologists can work as chemistry bench specialists, chemistry section leads, POCT coordinators, or advance into method development and validation roles in clinical laboratories.
