Q & A
Who is Dr. Gabriel Pascal, and what are his qualifications?
-Dr. Gabriel Pascal is the founder and CEO of Legend Review Center. He placed second in the March 2021 Physician Licensure Exam and also second in the September 2014 Med Tech Licensure Exam. He has a bachelor's degree in Medical Laboratory Science from St. Louis University.
What was the highest and average score in the pre-test mentioned by Dr. Pascal?
-The highest score in the pre-test was 29, and the average score was around 16.94.
What is a Westgard rule, and which rule is considered only as a warning rule?
-Westgard rules are quality control rules for clinical laboratory testing to ensure the accuracy and precision of test results. The 1 2s rule is considered only as a warning rule and would not result in the rejection of results.
What is the main cause of a shift observed in a control chart according to the script?
-The main cause of a shift observed in a control chart is improper calibration.
Why is a triglyceride value of 1036 mg/dL of immediate concern, and which condition is it associated with?
-A triglyceride value of 1036 mg/dL is of immediate concern because it is associated with pancreatitis. Very high triglyceride levels increase the risk of developing this condition.
Which lipoprotein migrates farthest from the anode during electrophoresis, according to the webinar?
-Chylomicrons migrate farthest from the anode during electrophoresis.
What is the characteristic feature of rice water stools, and which disease is it a hallmark of?
-Rice water stools are characterized by profuse water diarrhea leading to dramatic fluid loss, severe dehydration, and hypotension. It is a hallmark of cholera toxin activity caused by Vibrio cholerae.
What differentiates Class I, II, and III biological safety cabinets as discussed in the webinar?
-Class I safety cabinets have an open front and sterilized room air enters, passing through a HEPA filter before being exhausted. Class II cabinets have laminar flow with air filtered both before entering and exiting. Class III cabinets are completely enclosed with negative pressure inside.
In the context of the webinar, how are indole positive, MR positive, VP negative, and citrate negative results interpreted?
-The biochemical test results of indole positive, MR positive, VP negative, and citrate negative indicate the presence of E. coli.
What is the infective stage of the parasite causing cholera, and how is it transmitted according to the script?
-The infective stage of the parasite causing cholera is the cyst stage, and it is transmitted through ingestion. Once ingested, the cyst undergoes excystation in the small intestine, and the resulting trophozoites inhabit the large intestine.

📚 Introduction and Overview of the Webinar
The webinar begins with a welcome address, introducing the topic as 'Trends in the Magic Licensure Exam.' The speaker, Dr. Gabriel Pascal, is introduced as the founder and CEO of Legend Review Center. He shares his academic and professional achievements, including his high rankings in medical exams and his educational background. The webinar's purpose is to discuss questions from the last board exam, based on student feedback. A brief analysis of the pre-test scores is provided, with the highest score being 29 and an average score of 16.94. The first subject discussed is clinical chemistry, which was reportedly easy compared to other subjects in the last board exam.
🧪 Westgard Rules and Quality Control
This segment delves into the Westgard rules, which are used in quality control for medical testing. The speaker explains that these rules help detect both random and systematic errors in test results. The different types of Westgard rules are discussed, including the warning Rule (Rule 1) and rejection rules (Rules 2-10). Specific examples of violations such as 1S, 2S, 3S, 4S, and 10X are provided, along with explanations of what they indicate. The importance of understanding these rules for quality control in medical testing is emphasized.
📊 Interpretation of Control Charts and Errors
The speaker discusses the interpretation of control charts, focusing on the identification of trends and shifts in control values. A trend is defined as a consecutive increase or decrease in control values over six branches, typically indicating a deterioration of reagents. A shift is identified when six consecutive control values are on the same side of the mean, usually due to improper calibration. The speaker also covers the identification of outliers and their significance in medical testing.
🩸 Clinical Cases and Lipid Profiling
This part of the webinar addresses clinical cases, including the interpretation of triglyceride levels and their association with pancreatitis. The speaker highlights the importance of recognizing high triglyceride levels as a potential risk factor for pancreatitis. Additionally, the webinar covers the migration patterns of lipoproteins during electrophoresis, identifying HDL as the farthest from the anode and explaining the arrangement of lipoproteins in electrophoresis.
🦠 Identification of Microorganisms and Biochemical Tests
The speaker discusses the identification of microorganisms based on their biochemical characteristics. Specific tests like indole, MR, VP, and citrate tests are explained, with E. coli and Klebsiella species highlighted as examples. The importance of understanding these tests for accurate identification of bacteria in clinical settings is emphasized.
🌐 Parasitology and Stool Specimens
This section focuses on parasitology, particularly the identification of amoeba in stool specimens. The speaker describes the life cycle of amoebic infections and the stages that can be observed in stool samples. The importance of recognizing the infective stage (cyst) in the diagnosis and treatment of parasitic infections is discussed.
🔬 Safety Cabinets and Parasitology Identification
The speaker discusses different classes of biological safety cabinets, explaining their functions and the level of protection they offer. The classification of cabinets as Class I, II, and III is covered, with details on air filtration and pressure differences. Additionally, the identification of parasites in stool samples is discussed, with the 'Japanese Lantern egg' as an example.
💧 Clinical Microscopy and Hematology
This segment covers topics in clinical microscopy and hematology. The identification of various crystals and RBCs in urine samples is discussed, along with the significance of hypotonic and hypertonic urine. The speaker also covers the coagulation pathways, focusing on the role of protein S and protein C in anticoagulation. The importance of understanding these pathways for diagnosing and treating coagulation disorders is highlighted.
🩸 Hematology and Transfusion Medicine
The speaker discusses various aspects of hematology, including the production of erythropoietin and its role in treating anemia associated with kidney disease. The functions of protein S and the significance of PT and APTT tests are explained. The speaker also covers the use of fresh frozen plasma (FFP) in treating various conditions and the importance of considering coagulation factors produced by the liver.
🧬 Laboratory Practices and Continuing Education
The final segment touches on laboratory practices, including the correction of BCS stacking using the saline replacement technique and the interpretation of rheumatoid factor tests. The speaker also discusses the primary indications for transfusion and the preparation of formaldehyde solutions.
