ExploreAbout this exam
SH - Specialist in Hematology - is one of the credentials listed by the ASCP Board of Certification (BOC), appearing on the BOC site as 'SH – Specialist in Hematology' within the Hematology area of interest. The BOC also lists a separate H (Scientist in Hematology) credential, so candidates should confirm which examination matches their education and experience before applying; the site's Eligibility Pathways pages and Eligibility Assistant exist for exactly that purpose. The specialist examination is aimed at laboratory professionals who already work in hematology and want formal recognition of advanced, bench-level and interpretive expertise. Content follows the field's major practice areas: normal hematopoiesis and erythrocyte physiology; anemias and other erythrocyte disorders; benign and malignant leukocyte disorders; hemostasis and coagulation; and laboratory operations, quality, and instrumentation. Preparation is self-directed. The BOC publishes Content Guidelines & Reading Lists and Examination Readiness Resources, and its Examination Process pages explain scheduling, the test center, and results. Credential holders maintain the SH through the BOC's Credential Maintenance Program. No question count, time limit, fee, or passing score is stated in the material this page was built from, so confirm current figures on the ASCP BOC site.
What you'll study
About ASCP SH preparation
Is the SH the same as the H credential?
No. The ASCP BOC lists them as separate credentials: H is Scientist in Hematology and SH is Specialist in Hematology. They have separate overview pages, separate applications, and separate maintenance records. Review both Eligibility Pathways pages before you submit anything, and choose the one that matches your degree and your documented laboratory experience.
What is the exam format?
It is a multiple-choice credential examination delivered at a testing center; the BOC maintains an Examination Process section covering about the examination, scheduling, the test center, and results. The retrieved BOC content does not state an item count, time limit, or detailed delivery rules, so consult the About the Examination page for current specifics rather than secondhand figures.
How many questions and how much time do I get?
Those figures are not given in the source material this page was built from, so no number is published here. Item counts and time limits are set by the BOC and can be revised between administrations. Check the About the Examination page and your scheduling confirmation before you plan a pacing strategy.
What score do I need to pass, and when do I get results?
The passing standard is set by the BOC and is not reported in the retrieved source, so treat any number you hear as unverified. Results handling is described on the BOC's Examination Results page. Do not budget study time around a rumored cut score; aim for broad competence across every content area instead.
If I fail, can I retake it?
Retake rules, waiting periods, and any associated fees are governed by the BOC's application policies, which the retrieved content does not quote. Read the Application Policies and After the Examination pages before you apply, because the conditions attached to a first attempt are not always the same as those for a repeat attempt.
How should I order my study?
Start with normal hematopoiesis and erythrocyte physiology, because morphology, red cell indices, and interpretation in the anemia and leukocyte sections all assume it. Then work through anemias, then benign and malignant leukocyte disorders, then hemostasis and coagulation. Keep laboratory operations, quality, and instrumentation running throughout, since it interacts with every other area.
What are the common failure modes?
Candidates typically lose points by memorizing morphology without the underlying mechanism, by underpreparing coagulation logic and mixing-study interpretation, and by treating quality control, calibration, and interference as an afterthought. Another frequent problem is misreading the stem: the single best answer is often the next appropriate test rather than the diagnosis itself.
How do I keep the SH after I pass?
Specialist credentials are maintained through the BOC's Credential Maintenance Program. The Maintain Your Credentials section lists SH – Specialist in Hematology among the credentials to maintain and explains how continuing education points are earned and allocated. Record points as you earn them rather than reconstructing a cycle at the last minute.
Where do I find the official reading lists?
The BOC publishes Content Guidelines & Reading Lists under Examination Preparation Resources, alongside Examination Readiness Resources. Use the content guidelines to map the exam's scope, then commit to two or three texts. Depth in one solid hematology reference beats skimming five, especially in morphology and hemostasis.
