Interpretation and Clinical Correlations
Start with the big picture
The topic organizes laboratory interpretation across several clinical areas. Acid–base assessment includes anion gap metabolic acidosis, respiratory acidosis, and the serum osmol gap. Cardiac markers include troponin and BNP, while liver assessment considers aminotransferase patterns, ALP with GGT, albumin, and bilirubin. Renal and electrolyte interpretation covers eGFR, the BUN/creatinine ratio, sodium correction, and corrected calcium. The material also introduces HbA1c, thyroid testing, ferritin, and CRP. Across these examples, interpretation depends on recognizing patterns and considering context: a result may guide a differential, but should not be read in isolation.
What you'll learn
- Recognize laboratory patterns associated with anion gap and respiratory acidosis.
- Describe how cardiac markers contribute to assessment of myocardial injury and heart failure.
- Compare liver enzyme and protein patterns used in hepatobiliary interpretation.
- Interpret selected renal, electrolyte, endocrine, and hematologic markers.
- Identify clinical context that can affect interpretation of laboratory results.
