Question

A 52-year-old man went to his physician for a physical examination. The patient had been a district manager for an automobile insurance company for the past 10 years and was 24 pounds overweight. He had missed his last two appointments with the physician because of business. The urinalysis dipstick finding was not remarkable. His blood pressure was elevated. The blood chemistry results are listed in Case Study Table 15-1.1. Given the abnormal tests, what additional information would you like to have? If this patient had triglycerides of 100 mg/dl. (1.1 mmol/L) and an HDL-C of 23 mg/dL (0.6 mmol/L). what would be his calculated LDL-C value? If, however, his triglycerides were 476 mg/dL (5.4 mmol/L), with an HDL-C of 23 mg/dL (0.6 mmol/L). what would be his calculated LDL-C value?

Explanation / Answer

1. Given the very high BUN value, and low total protein and albumin values, it can be suggested that the high BUN value of the patient is not due to a very high protein intake in their diet. The bilirubin values are slightly high than normal, which maybe due to fasting. Thus, it has to be mentioned if the patient had taken the test in or without a fasting condition. A GFR test is required to be done along with the above in order to check for the kidney function test.

To calculate LDL the formula is Total cholesterol- HDL- (Triglycerides/5)

2. LDL= Total cholesterol- HDL- (Triglycerides/5)

= 210- 23- (100/5)

= 167 mg/dL

3. LDL= Total cholesterol- HDL- (Triglycerides/5)

= 210- 23- (476/5)

= 91.8 mg/dL
