MTLE Hematology and Blood Banking + Serology Strategy
MTLE hematology and blood banking + serology share patterns and rules. Here's how Filipino medtech reviewers should rotate them for maximum efficiency.

Why MTLE Hematology and Blood Banking Reward Joint Review
MTLE hematology and blood banking + serology are technically separate board subjects, but they share so much underlying biology that joint review wins. Both involve red cells, immune system reactions, and laboratory testing patterns. Around 6,000 medtech graduates sit MTLE per cycle, with the next sitting on August 15–16, 2026 under the PRC Board of Medical Technology. Reviewers who rotate these subjects together gain efficiency they can spend on weaker content elsewhere. Here's how to do it.
What MTLE Hematology Tests
1. RBC Indices and Anemias
- MCV, MCH, MCHC calculations and interpretation
- Microcytic (iron deficiency, thalassemia, anemia of chronic disease)
- Macrocytic (B12, folate, MDS)
- Normocytic (acute blood loss, hemolytic, aplastic)
- Reticulocyte count interpretation
2. Smear Morphology
- Target cells (thalassemia, liver disease)
- Spherocytes (hereditary spherocytosis, autoimmune hemolytic)
- Schistocytes (microangiopathic hemolytic anemia, DIC, TTP)
- Sickle cells (sickle cell disease)
- Howell-Jolly bodies (post-splenectomy, megaloblastic)
- Basophilic stippling (lead poisoning, thalassemia)
3. WBC Differential and Disorders
- Normal differential percentages
- Leukemias (acute vs chronic, lymphoid vs myeloid)
- Reactive vs malignant changes
- Auer rods (AML)
4. Coagulation
- PT, APTT, TT interpretation
- Coagulation cascade (intrinsic, extrinsic, common pathway)
- DIC, hemophilia, von Willebrand
- Anticoagulant monitoring (heparin, warfarin)
What MTLE Blood Banking Tests
1. Blood Group Systems
- ABO (forward and reverse typing, discrepancies)
- Rh (D antigen, weak D testing)
- Other systems (Kell, Duffy, Kidd, MNS)
2. Antibody Screening and Identification
- Indirect antiglobulin test (IAT)
- Direct antiglobulin test (DAT/Coombs)
- Antibody panel interpretation
- Cold vs warm antibodies
3. Compatibility Testing
- Major and minor crossmatch
- Type and screen vs type and crossmatch
- Emergency release protocols
4. Transfusion Reactions
- Acute hemolytic (ABO mismatch, fatal)
- Febrile non-hemolytic
- Allergic, anaphylactic
- TRALI, TACO
- Delayed hemolytic
5. Component Therapy
- Whole blood, packed RBC, platelets, FFP, cryoprecipitate
- Storage temperatures and shelf life
- Indication for each component
What MTLE Serology Tests
Serology overlaps with blood banking on antigen-antibody reactions but extends into infectious disease serology:
- Syphilis tests (VDRL, RPR, FTA-ABS, TPPA)
- Hepatitis serology patterns (HBsAg, anti-HBs, anti-HBc IgM/IgG, HBeAg)
- HIV testing algorithm
- Rheumatologic markers (RF, ANA, anti-CCP)
- Streptococcal antibodies (ASO, anti-DNase B)
- Pregnancy testing (hCG)
The 4-Week Joint Review Block
Week 1: Hematology Foundations
RBC indices, anemia classification, smear morphology. Image-based drills daily.
Week 2: Hematology Advanced + WBC + Coagulation
Leukemias, coagulation testing, bleeding disorders.
Week 3: Blood Banking Foundations
ABO/Rh typing, antibody screening, compatibility testing, transfusion reactions, components.
Week 4: Serology + Mixed Mocks
Hepatitis serology patterns, HIV algorithm, syphilis. Mixed hematology + blood banking + serology mocks every other day.
The Patterns That Show Up Every Cycle
- Iron deficiency vs thalassemia minor differentiation (MCV, RDW, RBC count, ferritin)
- Smear identification (target cells, schistocytes, sickle cells, Auer rods)
- Hepatitis B serology window phases
- ABO discrepancy resolution
- Acute vs delayed hemolytic transfusion reaction signs
- Coagulation factor pathway mapping (which factor extends which time)
- Component shelf life and storage temps
The Hepatitis B Serology Question Pattern
Every MTLE has at least one hepatitis B serology interpretation. The patterns:
- Acute infection: HBsAg+, anti-HBc IgM+
- Chronic infection: HBsAg+ for 6+ months
- Resolved infection: anti-HBs+, anti-HBc IgG+
- Vaccinated: anti-HBs+ only
- Window period: anti-HBc IgM+ only (HBsAg cleared, anti-HBs not yet present)
Drill these as a single themed flashcard set. Free points if you have it down.
The ABO Discrepancy Question Pattern
Forward typing (anti-A, anti-B reagents on patient cells) and reverse typing (A1 and B reagent cells against patient serum) should match. When they don't, you have a discrepancy. Common causes:
- Cold antibodies (more common in elderly)
- Subgroup of A (A2 with anti-A1)
- Acquired B antigen
- Recent transfusion
- Hypogammaglobulinaemia (newborns, elderly)
How These Subjects Compare Across MTLE
Hematology has the highest visual recognition demand. Blood banking has the most rule-based logic (ABO/Rh tables, transfusion compatibility). Serology is mostly pattern-recall. Together they're roughly 30–35% of the total exam — substantial. See our clinical chemistry guide and microbiology guide for the rest of the subjects.
Pacing on Exam Day
Hematology smear questions should average 45 seconds. Blood banking compatibility questions average 60–75 seconds because of the reasoning involved. Serology pattern questions average 30 seconds. Plan accordingly.

FAQ
Why review hematology and blood banking together?
The biology overlap saves time. Both involve RBC antigens, antibody-mediated reactions, and similar laboratory methods.
Are smear images really tested on MTLE?
Yes, every cycle. Image-based item drills are non-negotiable for hematology.
How much serology coverage?
Hepatitis serology, HIV, syphilis, RF/ANA basics. Roughly 5–8 items per cycle.
Should I memorise the entire coagulation cascade?
Memorise enough to answer 'which factor deficiency extends which time?' Intrinsic (APTT), extrinsic (PT), common (both). That covers most exam items.
