Welcome to Jing-Meng Diagnosis Clinical Chemistry

From past decades JM’s Clinical Chemistry laboratories have provided a wide breadth and depth of tests from routine to esoteric. Our automated in-house developed technology performed high accuracy clinical chemistry based diagnostic results, which is a state of art integral part of JM’s laboratories. JM’s automated systems allow for rapid turnaround times, optimal efficiency, and the best quality the industry has to offer.

Clinical chemistry

Clinical chemistry uses chemical processes to measure levels of chemical components in body fluids. The most common specimens tested in clinical chemistry are blood and urine. Many different tests exist to test for almost any type of chemical component in blood or urine. Components may include blood glucose, electrolytes, enzymes, hormones, lipids (fats), other metabolic substances, and proteins.

Clinical Chemistry Tests

The following is a description of some of the most common JM’s clinical chemistry tests (used on blood and urine specimens) including some of the uses and indications:

Blood glucose, or blood sugar, levels indicate how the body handles glucose. Measuring glucose levels after fasting (when the patient has not eaten anything for 8 hours) can help diagnose diabetes or hypoglycemia (low blood sugar).

Electrolytes include sodium, potassium, chloride, bicarbonate, calcium, phosphorus, and magnesium. Measuring electrolytes can specifically indicate certain metabolic and kidney disorders. Enzymes are released into the blood by organs that are damaged or diseased. The type of enzyme released can indicate which organ is affected:

Enzyme Organ affected
Creatine kinase Can signal damage to heart muscle or skeletal muscle CK-MB, an isoenzyme of CK, is used to distinguish heart muscle damage
Alanine aminotransferase (ALT, SGPT), aspartate aminotransferase (AST, SGOT) Can signal liver disorders
Amylase and lipase Can signal inflammation or the possibility of cancer of the pancreas

Hormones are secreted by the various endocrine glands to regulate the processes of the body. Raised or lowered levels of certain hormones can indicate over- or under-activity of those glands:

Hormone Gland Affected
Cortisol adrenal glands
Thyroxine (T4), TSH thyroid gland
FSH, ACTH, growth hormones pituitary gland

Lipids are fatty substances such as triglycerides (body fat), phospholipids (part of cell membranes), and sterols (such as cholesterol). Lipids can help signal coronary heart disease and liver disease:

Lipid Organ affected
Total cholesterol High total cholesterol is a risk factor for cardiovascular disease (CVD)
High-density lipoprotein (HDL or "good" cholesterol) Low-density lipoprotein (LDL or "bad" cholesterol)High LDL cholesterol is also a risk factor for CVD High HDL cholesterol is a protective factor against CVD
Triglycerides High triglycerides are another independent risk factor for CVD

Other metabolic substances can be measured to evaluate organ function:

Metabolic product Organ affected
BUN (blood urea nitrogen) Creatinine Kidney function
Uric acid Can signal gout, kidney disease, and other tissue damage

Proteins can indicate metabolic and nutritional disorders, as well as certain cancers:

Protein Organ affected
Total protein and albumin Can signal liver or kidney disease, or malnutrition
Globulins and the A/G ratio (albumin to globulin) Can signal infection, autoimmune disease, inflammation, and certain blood cancers

Often, abnormal blood and urine tests are repeated to make sure there is not a sample error or lab error. Abnormal tests we often followed up by other more specialized tests.
