CKMB
The VLDL-C/Triglyceride ratio in patients with this problem is > 0.3:
Dysbetalipoproteinemia
The following statement describes CORRECTLY chylomicrons & VLDL:
• Chylomicrons forms a creamy top layer, while VLDL leads to turbid serum/plasma
• both Chylomicrons & VLDL forms a creamy top layer
• both Chylomicrons &VLDL leads to turbid serum/plasma.
• all the above
• Chylomicrons leads to turbid serum/plasma, while VLDL forms a creamy top layer.
• none of the above
Chylomicrons forms a creamy top layer, while VLDL leads to turbid serum/plasma
A blood specimen is drawn for lipoprotein phenotyping. The test results obtained are
Triglyceride, 235 mg/dL (reference range, 40-164 mg/dL)
Total cholesterol, 190 mg/dL(reference range, less than 200 mg/dL)
Prebeta lipoprotein fraction increased
Beta lipoprotein fraction normal
Chylomicrons present
Serum appearance milky
The best explanation for these results would be that the individual exhibited characteristics of
• Type 1 hyperlipoproteinemia
• Type 11 hyperlipoproteinemia
• Type 1V hyperlipoproteinemia
• Type 1 hyperlipoproteinemia & Type 11 hyperlipoproteinemia
• A normal individual
Type 1 hyperlipoproteinemia
Corneal opacification can occur in patients with this dyslipidemia:
ApoA-1 deficiency and ApoC-III deficiency & ApoA-I variants
Mr. Smith, 77y.o., came in for an executive check-up. The following are his laboratory results: FBS = 150mg/d
(Normal 50-110mg/dl); Total Cholesterol = 250mg/dL; HDL = 20mg/dL; Creatine Kinase = 120 IU/mL. He
claimed he is well. What is your clinical impression?
Probable diabetic, with increased cholesterol, and normal CK result
These Dyslipidemia present with high cholesterol, elevated LDL-C, but with normal triglycerides, EXCEPT: • Familial hypercholesterolemia • Diabetic dyslipidemia • Sitosterolemia • Family defective apoB
Diabetic dyslipidemia
A 40 y.o. patient was rushed to the emergency room fur to difficulty of breathing. Chest X-ray show bilateral
pleural effusion. Thoracentesis was done which revealed whitish, cloudy fluid. Which of the following findings
will confirm a Chylothorax condition?
• triglycerides values 2.3mmol/l; cholesterol 7mmol/L
• triglycerides values 1.2 mmol/l; cholesterol 5.5mmol/L
• none of the above
• triglycerides values 2.0mmol/l; cholesterol 5mmol/L
• all the above
• triglycerides values 1.0mmol/l; cholesterol 6.8mmol/L
triglycerides values 2.0mmol/l; cholesterol 5mmol/L
The signs and symptoms of chylomicron retention disease appear in the first few months of life and they include the following EXCEPT: • Hypercholesterolemia • Failure of weight-gain and growth • Diarrhoea & Vomiting • none of the above • Steatorrhea
Hypercholesterolemia
A baby was born to a mother who had no prenatal check-up, & who is not sure of her AOG because of
irregular menses. The baby was observed to exhibit deep difficult breathing, & was developing cyanosis
(bluish skin discoloration). Which of these fetal amniotic fluid test results will be the best explanation?
• Lecithin : Sphingomyelin ratio = 2.0
• Lecithin : Sphingomyelin ratio = 1.2
• Lecithin : Sphingomyelin ratio = 2.8
• Lecithin : Sphingomyelin ratio = 1.5
• none of the above
• Lecithin : Sphingomyelin ratio = 2.8 & Lecithin : Sphingomyelin ratio = 1.5
Lecithin : Sphingomyelin ratio = 1.2
Standing Plasma Test is done to determine by visual inspection.
Chylomicrons
