The SCFHS exam for medtechs: the Technician paper, the Microbiology Technician paper and the SLLE
The SCFHS exam for medtech, explained from SCFHS's own guides: items, time, pass marks, the technician blueprint and the SLLE sections.
If you are a Filipino medtech looking at Saudi Arabia, the SCFHS exam for medtech is not one paper. SCFHS, the Saudi Commission for Health Specialties, publishes separate guides for the Laboratory Technician, the Laboratory (Microbiology) Technician and the Laboratory Specialist. Each has its own item count, clock and pass rule.
This post sets out what those three guides say, and only that. Where the guides are silent, such as attempt limits and who may sit which paper, we say "check with SCFHS" instead of guessing. For the other authorities, our comparison of the Gulf lab licensing exams keeps each one apart.
Which SCFHS exam for medtech is yours?
Your exam depends on the title SCFHS assigns you, and SCFHS publishes three laboratory guides: the Laboratory Technician, the Laboratory (Microbiology) Technician and the Laboratory Specialist (the Saudi Laboratory Specialist Licensure Examination, or SLLE). The guides do not say which Philippine degree or experience maps to which title.
That decision belongs to SCFHS, not to a review centre or a prep website. SCFHS's general classification page we opened has no laboratory-specific rules, and the attempt and eligibility lines are not in the guides. So before you buy any materials, ask SCFHS which exam your file leads to.
Two points help you plan in the meantime. The technician and specialist papers differ in length, in time, and in how they are scored. Practising for the wrong one wastes weeks. Our post on technician, technologist and specialist titles shows how the titles are handled across authorities.
What are the SCFHS exam formats side by side?
SCFHS's three laboratory papers differ in length and scoring, and the table below gives each as published. The technician figures come from SCFHS's Laboratory Technician blueprint and its Microbiology Technician guideline. The specialist figures come from the SLLE content guideline.
| Exam | Items | Time | Pass mark |
|---|---|---|---|
| Laboratory Technician (S1) | 150 MCQs | 3 hours | 55% |
| Laboratory (Microbiology) Technician (S3) | 150 MCQs | 3 hours | 55% |
| Laboratory Specialist, SLLE (S2) | 200 MCQs, which may include up to 10% pilot items | Two parts of 120 minutes, 30-minute break | 530 on a 200–800 scale |
The technician guide states the 55% mark applies to tests conducted from 21 June 2022. SCFHS also says the blueprint percentages are subject to change at any time, so read the current PDF before you book.
What is on the SCFHS Laboratory Technician exam?
The Laboratory Technician exam is 150 multiple-choice questions in 3 hours, and the passing score is 55%. That works out to 72 seconds an item if you spread the clock evenly, a pace we cover in our time management guide.
The same guide gives the blueprint by discipline. Microbiology, Clinical Chemistry, Hematology and Blood Bank are 20% each. Immunology/Serology is 15%, and Histo/Cyto-Techniques is 5%. Those six weights add up to 100%.
SCFHS adds a caveat that matters for planning: the distribution "may differ up to +/-5%" in each category. A 20% block can therefore land anywhere from roughly 15% to 25% of your paper. Do not treat 5% Histo/Cyto as skippable; a thin block still carries real points.
How is the technician blueprint split, and how does it compare with the SLLE?
The technician blueprint has six categories, while the SLLE guide lists nine sections with ranges instead of fixed weights. The table puts the two side by side. A dash means that category is not listed in that guide.
| Discipline | Technician weight (S1) | SLLE range (S2) |
|---|---|---|
| Microbiology | 20% | 15–20% |
| Clinical Chemistry | 20% | 15–20% |
| Hematology | 20% | 15–20% |
| Blood Bank | 20% | 15–20% |
| Immunology/Serology | 15% | 5–10% |
| Histo/Cyto | 5% | 5–10% |
| Urinalysis and Body Fluids | not listed | 5–10% |
| Laboratory Operations | not listed | 5–10% |
| Patient Safety and Professionalism | not listed | 5–10% |
Both guides rest on four big disciplines. If your target is the technician paper, those four are 80% of the exam. Our blood bank and hematology guide covers two of them in depth.
What is the SCFHS Microbiology Technician exam?
The Laboratory (Microbiology) Technician exam is also 150 MCQs in 3 hours with a 55% pass mark, but its content is narrower. SCFHS's guideline splits it into Laboratory Safety 10%, Quality Control 10%, Bacteriology 40%, Immunology/Serology 10%, Virology 10%, Mycology 10% and Parasitology 10%.
Bacteriology alone is 40%, so a candidate for this paper should spend close to half of their review there. Safety and QC together add another 20%, which is easy to underestimate because they feel like common sense. They are also the areas where wording matters most.
If you work at a microbiology bench, check that your title leads to this paper, not the general technician paper. The guides do not decide that for you. The general technician paper treats microbiology as one 20% block among six, so the two papers need very different study plans.
What is the SLLE, the Laboratory Specialist exam?
The SLLE is the Laboratory Specialist exam: 200 MCQs, which may include up to 10% additional pilot questions, in two parts of about 100 items each (plus or minus 10). Each part is 120 minutes, with a 30-minute break between them. Every item has four options and one best answer.
The pass score is 530 on a reporting scale of 200 to 800. SCFHS's guide says that figure was recommended in a standard-setting exercise in November 2019. It is a scaled score, so do not turn it into a percentage; the scale does not work that way, and any such figure is invented.
Pace is different here. Each 100-item part gets 120 minutes, so you have roughly 72 seconds an item per part, and a pilot item looks like any other. The 30-minute break is the only break we can source for any SCFHS paper. Your own preparation should include a full 200-item rehearsal.
What do the SCFHS guides not say?
The three SCFHS guides do not state how many times you may sit, whether a technician and a specialist have different eligibility, or which test provider runs the exam. They also describe no technologist exam, so nobody can honestly quote a format or pass mark for one.
That last point matters because some prep sites circulate numbers that conflict with SCFHS's own documents. If a figure is not in the guide for your exam, treat it as unverified. Do not plan your attempts around a number you cannot trace.
Here is what to ask SCFHS in writing:
- Which laboratory exam applies to my title and file?
- How many attempts do I have, and is there a waiting period?
- Which test provider and centre will SCFHS assign?
- What documents does my licensing file need before I can book?
Booking is not covered in these guides, so we describe delivery only as the test provider SCFHS assigns.
How can you practise for these papers with TerumoEdge?
TerumoEdge Gulf MLS Ex-Sim is a practice simulator, and we publish this blog, so weigh our advice accordingly. It holds 4,000 items across eight lab disciplines, with 500 in each, and every item has an English explanation giving the correct answer and why each other option is wrong.
Its Full Mock is one 100-item blend, not an SCFHS paper. The blend draws 18 items each from Blood Banking, Clinical Chemistry, Hematology and Clinical Microbiology, and 7 each from the other four. There is no separate mock per authority.
You can adjust the clock. To rehearse the 72-second pace of a 150-item, 3-hour technician paper, set the mock to 120 minutes. Discipline practice then lets you lean toward your blueprint's heavier blocks. Try the free 40-item demo first; it is unscored and shows no explanations.
Frequently asked questions
What is the SCFHS passing score for medtechs?
For the Laboratory Technician and the Laboratory (Microbiology) Technician exams, SCFHS publishes a passing score of 55%. For the Laboratory Specialist exam (SLLE), the pass score is 530 on a 200–800 reporting scale. SCFHS says percentages may change, so check the current guide for your exam.
How many items is the SCFHS lab exam?
The two technician papers are 150 MCQs each, with 3 hours. The SLLE is 200 MCQs, which may include up to 10% pilot items, in two 120-minute parts with a 30-minute break. The item count depends on which exam your title leads to.
Is 530 out of 800 a percentage?
No. The 530 is a pass score on a reporting scale that runs from 200 to 800, set in a November 2019 standard-setting exercise. It cannot be converted into a percentage of correct answers, so do not compare it with the 55% technician mark.
How many times can I take the SCFHS exam?
The SCFHS laboratory guides we read do not state attempt limits or waiting periods. Figures you may see elsewhere do not come from those guides. Check with SCFHS for the rules that apply to your file before you plan around a number.
