- ABB's ELD path requires passing two exams: Embryology Laboratory Administration and Embryology.
- Same-day testing of both exams costs $525 versus $355 for a single exam.
- General Regulation 19 requires 60 personally performed completions in each listed ART procedure category.
- Certification demands 24 CE hours every 2 years plus annual revalidation and PEER participation.
How to Use This Cheat Sheet
This page is a compressed reference, not a substitute for deep preparation. Treat it as the single sheet you glance at the night before your exam or during a five-minute study break between shifts. If a fact here feels unfamiliar, that's a signal to go back to the full ELD Study Guide 2026: How to Pass on Your First Attempt and rebuild the underlying knowledge rather than memorizing the line item in isolation.
Everything below is organized around what actually shows up on the American Board of Bioanalysis (ABB) exams: the administrative rules that govern eligibility and renewal, and the 17 technical and managerial domains tested in the Embryology and Embryology Laboratory Administration exams.
Certification Mechanics at a Glance
Before drilling embryo grading or cryoprotectant chemistry, lock in the administrative skeleton of the credential. This is the part candidates lose points on simply by not reading the fine print - and it's covered in more depth in ELD Certification.
- Certifying body: American Board of Bioanalysis (ABB)
- Exams required: Embryology Laboratory Administration + Embryology (two separate exams)
- Application fee: $420
- Standards effective date: December 28, 2024
- Validity period: Through December 31 of the year granted
- Ongoing requirements: Annual revalidation, PEER participation, 24 CE contact hours every 2 years
Key Takeaway
Because certification expires December 31 of the year it's granted, schedule your exam early in the year rather than in Q4 to maximize your first full certification cycle before revalidation obligations begin.
All 17 Domains - Quick Reference
The ELD exams pull from 17 distinct content areas spanning bench technique, clinical science, and laboratory management. A full breakdown of each is available in the ELD Exam Domains 2026: Complete Guide to All 17 Content Areas, but here is the fast-scan list:
| # | Domain | Category |
|---|---|---|
| 1 | Culture Techniques | Technical/Bench |
| 2 | Embryo Development and Embryo Transfer | Technical/Clinical |
| 3 | Insemination and Documentation of Fertilization | Technical/Bench |
| 4 | Cryopreservation | Technical/Bench |
| 5 | Gamete Collection and Preparation | Technical/Bench |
| 6 | Micromanipulation | Technical/Bench |
| 7 | Genetic Diagnosis | Technical/Clinical |
| 8 | QA/QC | Management |
| 9 | Safety and Regulatory Compliance | Management |
| 10 | Female Reproductive Physiology | Clinical Science |
| 11 | Infertility | Clinical Science |
| 12 | General Laboratory Management | Management |
| 13 | CLIA Regulation | Regulatory |
| 14 | OSHA & Laboratory Safety | Regulatory |
| 15 | FDA & Reproductive-Tissue Regulation | Regulatory |
| 16 | Employment & Laboratory Law | Management/Legal |
| 17 | Basic Blood Collection & Endocrinology | Clinical Science |
High-Yield Facts by Content Cluster
Rather than treating all 17 domains as equally weighted trivia, group them into functional clusters. This mirrors how questions are actually written - they test judgment within a workflow, not isolated vocabulary.
Bench and Procedural Cluster (Domains 1, 3, 4, 5, 6)
Culture Techniques, Insemination, Cryopreservation, Gamete Prep, Micromanipulation
These domains test hands-on protocol knowledge: media selection and pH/osmolality control, timing windows for fertilization checks, vitrification versus slow-freeze rationale, sperm processing methods, and ICSI/biopsy technique. Expect scenario-based items describing a specific lab situation and asking you to select the correct corrective action.
- Know the rationale behind each culture system, not just its name
- Understand cryoprotectant toxicity trade-offs and timing
- Recognize documentation requirements tied to fertilization assessment
Clinical and Developmental Cluster (Domains 2, 7, 10, 11, 17)
Embryo Development/Transfer, Genetic Diagnosis, Female Physiology, Infertility, Endocrinology
This cluster leans on applied physiology: hormonal cycles, ovarian stimulation protocols, embryo grading criteria, PGT indications and limitations, and basic phlebotomy/endocrine testing relevant to fertility monitoring. Questions often connect a lab finding to a clinical decision point.
- Map hormone levels to cycle phase and stimulation response
- Distinguish PGT-A, PGT-M, and PGT-SR use cases
- Connect embryo grading terminology to transfer decisions
Management and Compliance Cluster (Domains 8, 9, 12, 13, 14, 15, 16)
QA/QC, Safety, Lab Management, CLIA, OSHA, FDA, Employment Law
This is where the "Administration" exam concentrates. Expect items on proficiency testing, corrective action documentation, CLIA personnel requirements, OSHA bloodborne pathogen standards, FDA regulation of reproductive tissue (donor screening, tissue tracking), and employment law basics relevant to supervising lab staff.
- Know CLIA director responsibilities and how they differ from ELD scope
- Understand FDA donor-eligibility and tissue-tracking requirements
- Be able to identify QC failure triggers and required corrective steps
Eligibility Snapshot
Eligibility errors are a common reason candidates delay their exam date. Confirm all of the following before applying - the full breakdown lives in ELD Requirements 2026: Eligibility, Prerequisites & How to Qualify:
- Meet one of ABB's listed laboratory-director or doctoral-degree pathways
- Complete at least 32 semester hours in chemistry or biological sciences
- Have at least 2 years directing or supervising embryology testing on human specimens within the prior 10 years
- Satisfy ABB General Regulation 19, including 60 personally performed completions in each listed assisted-reproductive procedure category
That 60-completion requirement per category under General Regulation 19 is the detail most likely to be underestimated. It is procedural experience, not classroom hours, and it must be documented per category - not as an aggregate total.
Fee Table
Fee structure affects how you schedule your exams. Full cost context, including how these numbers compare across similar credentials, is in ELD Certification Cost 2026: Complete Pricing Breakdown.
| Item | Fee |
|---|---|
| Application fee | $420 |
| Embryology Laboratory Administration exam (alone) | $355 |
| One technical discipline exam (alone) | $355 |
| Both exams, same day | $525 |
Key Takeaway
Taking both exams on the same day saves money compared to two separate sittings ($525 combined vs. $710 if taken as two standalone $355 exams) - but only makes sense if you're equally prepared for both content areas.
The Week-Before Review Plan
General study methods like spaced repetition work best when mapped directly onto ELD's domain structure rather than applied generically. In the final week, sequence your review so bench-heavy domains get earlier, longer sessions and regulatory domains get late, high-frequency review - regulatory facts (CLIA, OSHA, FDA specifics) fade fastest from memory.
Bench and Procedural Cluster
- Re-derive protocols for Culture Techniques, Cryopreservation, and Micromanipulation rather than re-reading notes
Clinical and Developmental Cluster
- Drill hormone/cycle-phase mapping and embryo grading scenarios
Management and Compliance Cluster
- Rapid-fire CLIA, OSHA, and FDA regulation flashcards; these decay fastest
Full-Domain Pass
- Light review across all 17 domains, prioritizing anything flagged during practice testing
If you want a longer runway than one week, the multi-week structure in the ELD Study Guide 2026: How to Pass on Your First Attempt extends this same clustering logic across a full preparation cycle.
Common Mix-Ups to Avoid
- ELD vs. HCLD scope: ELD does not confer CLIA high-complexity director status on its own; HCLD does, and an HCLD in embryology can qualify automatically for ELD.
- Aggregate vs. per-category experience: The 60-completion requirement under General Regulation 19 applies per listed ART procedure category, not as a combined total.
- Exam fee assumptions: Same-day combined testing is $525, not simply the sum of two $355 fees.
- Certification expiration date: Certification runs through December 31 of the year granted - not a rolling 12-month or multi-year window before revalidation duties start.

Once your foundational review is solid, run timed practice sets on the ELD practice test platform to convert this cheat sheet's facts into exam-ready recall. Doing repeated scenario-based practice on our practice exams is the fastest way to see which of the 17 domains still need work before test day.
FAQ
Two: Embryology Laboratory Administration and Embryology. Both are ABB-administered and can be taken separately or on the same day.
No. ELD certification alone does not confer CLIA high-complexity laboratory director status; HCLD certification does. An HCLD earned in embryology can automatically qualify for ELD.
Taking both exams on the same day costs $525 total, versus $355 for each exam taken individually on separate occasions ($710 combined).
It requires embryology experience that includes 60 personally performed completions in each listed assisted-reproductive procedure category, in addition to the general experience and coursework eligibility requirements.
ABB requires 24 acceptable continuing-education contact hours every 2 years, along with annual revalidation and PEER program participation.
