Biochemistry Training and Lab Results Interpretation

Google "biochemistry lab results interpretation" to get a list of websites that will help.

Be careful when looking at the protocol and data; some are for animals and not humans.

The medical laboratory technologists (MLTs) are trained by the institution or by other institutions. They perform the lab tests on automated clinical chemistry laboratory analyzers. While most clinical lab tests are performed on automated analyzers, some tests have to be performed manually.

All clinical lab tests have a Quality Control (QC) program and a Quality Assurance Program (QAP) for the lab (UK NEQAS and Australian RCPA-QAP).

Not all clinical labs perform all the lab tests listed below.

Not all clinical labs categorise their lab tests as shown below.

UK and Malaysian clinical labs report lab data in SI Units; USA labs still use old units.

Lab tests are grouped into panels by chemistry, organ, disease, or disease process:
  1. Electrolytes: Sodium, potassium, chloride
  2. Acid-base: Bicarbonate and anion gap, acid-base disturbances
  3. Renal: Urea and creatinine
  4. Minerals: Calcium (total and ionized), phosphate, magnesium
  5. Proteins: Total protein, albumin, globulins, A/G ratio, ammonia, uric acid, electrophoresis
  6. Carbohydrates: Glucose, fructosamine and glycosylated hemoglobin, 
  7. Lipids: Triglycerides, cholesterol, non-esterified fatty acids (NEFA)
  8. Ketones: β-hydroxybutyrate (BHB)
  9. Liver: Enzymes (ALT, AST, SDH, GLDH, LDH, ALP, GGT), bilirubin (total, indirect, direct), bile acids, ammonia
  10. Pancreas: Amylase, lipase
  11. Muscle enzymes: AST, CK, LDH
  12. Iron: Iron, total iron binding capacity, % saturation, ferritin
  13. Interference indexes: Lipemia, hemolysis, icterus

The students of the Masters of Medicine (MMed) 4-year program have a basic MD or MBBS degree and at least 2 years work experience at a hospital before joining the program at the university. Topics covered in the MMed training covers some of the following:

QC and QA
Clinical Lab Management
Clinical Biochemistry (see 1-13 above)
Haematology and Coagulation
Adult Endocrinology
Pediatric Endocrinology
Metabolic Medicine
Nephrology
Neonatology
Cytogenetics
GI & Hepatology
Research
Electives (Toxicology, Nutrition TPN, Genetics)
Hospital posting (field work)

The MMed trainees in Chemical Pathology are competent to interpret lab tests data. These include:
  1. Calcium and metabolic bone disorders
  2. Diabetes mellitus: Plasma glucose, Glucose tolerance test (GTT), HbA1C
  3. Inherited metabolic disorders; Inborn Errors of Metabolism (IEM)
  4. Lipidology/Lipids: HDL, LDL cholesterol, Triglycerides, oxLDL
  5. Cardiovascular risk assessment/Heart attack markers: AST, LDH, Troponins, CKMB, Myoglobin, beta-type natriuretic peptide
  6. Nutrition
  7. Renal disease
  8. Thyroid disease: TRH, TSH, T3 and T4
  9. Liver disorder
  10. Tumour markers: Ca-125, Ca-119, Ca-153, oncogenes and specificity
  11. Arterial blood gases

The clinicians who teach in the MMed program are university lecturers and they serve as laboratory consultants; they also supervise the general running of the clinical lab and are paid a 'critical allowance' for doing so. They have a basic MD/MBBS degree and a postgraduate degree (MSc/MPath/MMed) in Chemical Pathology. At present, none have a PhD degree or FRCPath. None are professors.
