Clinical Biochemistry
Master the science of diagnostic medicine through biochemical analysis
What is Clinical Biochemistry?
Clinical biochemistry, also known as chemical pathology, is the branch of laboratory medicine that deals with the analysis of bodily fluids—such as blood, plasma, serum, and urine—for diagnostic and therapeutic purposes. This comprehensive clinical biochemistry guide serves as essential clinical biochemistry notes for students and professionals seeking to understand the fundamentals of clinical biochemistry.
The importance of clinical biochemistry in medicine cannot be overstated, as this field plays a crucial role in identifying diseases, monitoring treatments, and understanding the metabolic status of patients. By studying enzymes, electrolytes, lipids, proteins, hormones, and other biochemical substances through clinical biochemistry laboratory tests, this discipline provides essential data to guide healthcare decisions and supports clinical biochemistry in diagnosis across all medical specialties.

Biochemistry studies the chemical processes within living organisms, while clinical biochemistry applies these concepts to diagnose and manage diseases in humans. Clinical biochemistry is the practical application of biochemical knowledge in healthcare settings.
Certain enzymes are released into the blood when specific organs are damaged. Their presence and levels help identify organ dysfunction (e.g., ALT in liver disease, CK in muscle injury). This makes enzyme testing a valuable diagnostic tool for detecting tissue damage.
Some tumor markers (e.g., PSA, CA-125, AFP) used in clinical biochemistry can support cancer diagnosis, but further imaging and biopsy are usually needed for definitive diagnosis. These markers are more commonly used for monitoring treatment response and detecting recurrence.
Most tests involve simple blood or urine collection and are minimally invasive. Blood draws may cause brief discomfort, but the procedures are generally quick and well-tolerated. The diagnostic value far outweighs any minor discomfort experienced.
