Bone Metabolism
Osteocalcin as an indicator
Bones are continuously undergoing a dynamic process of resorption and absorption known as bone metabolism.
Signaling pathways on which bone metabolism rely include the action of several hormones, including Osteocalcin, parathyroid hormone (PTH) and Vitamin D. As Osteocalcin, the major non-collagenousprotein of the bone matrix, is manufactured by osteoblasts, it is often used as a biochemical marker, for the bone formation process.
A large number of studies indicate that serumosteocalcin levels reflect very well the rate of bone formation. The determination of blood levels of Osteocalcin is valuable for the identification of women at risk of developing osteoporosis Monitoring bone metabolism in several clinical conditions:
- During peri- and post menopause;
- During Hormone Replacement Therapy;
- Patients with GH deficiency, Renal osteodystrophy.
Cancer Markers
Serum tumor markers is a term commonly used to refer to molecules that can be detected in a blood sample by immunochemical methods.
Tumor markers are produced either by the tumor (cancer) itself or by the body in response to the presence of cancer or certain non-cancerous benign) conditions.
Drug of Abuse
DiaSource offers a rapid test for the diagnostic of Nicotine and Cotinine for drug of abuse. The purpose of this rapid chromatographic immunoassay is to detect Cotinine (nicotine metabolite) in human urine.
Cotinine is the first-stage metabolite of nicotine, a toxic alkaloid that produces stimulation of the autonomic ganglia and central nervous system when in humans. Nicotine is a drug to which virtually every member of a tobacco-smoking society is exposed whether through direct contact or second-hand inhalation.
In addition to tobacco, nicotine is also commercially available as the active ingredient in smoking replacement therapies such as nicotine gum, transdermal patches and nasal sprays.
Autoimmunity
Autoimmunity is an immune response of an human organism against its own cells and tissues. This aberrant immune response results in many different disease. These diseases are called autoimmune disease.
Examples include Celiac disease, diabetes mellitus type 1, Sarcoidosis, systemic lupus erythematosus (SLE), Sjögren's syndrome, Churg-Strauss Syndrome, Hashimoto's thyroiditis, Graves' disease, idiopathic thrombocytopenic purpura, Addison's Disease, rheumatoid arthritis (RA), Polymyositis (PM), and Dermatomyositis (DM).
Diagnosis of autoimmune disorders largely rests on accurate history and physical examination of the patient. In several systemic disorders, serological assays which can detect specific autoantibodies are employed: Autoantibodies are used to diagnose many autoimmune diseases and their levels are measured to determine the progress of the disease.
The actual growth in testing volumes – as appearance of autoimmune disorders is increasing steadily - will prompt clinical laboratories to employ advanced autoimmune disease diagnostic tests. Several autoimmune disease diagnostic tests however are designed for manual operation and the shortage of skilled technicians limits their use. This creates immense demand for automated diagnostic platforms that facilitate rapid and efficient testing.
The constant increase in new diagnostics parameters for autoimmune diseases, the evolution of clinical laboratory demands have led to the development of a complete new range of Auto-Immunity diagnostics kits.
DiaSource brings to market a totally new approach of auto-immune testing based on the latest state-of-the-art membrane technology (DOT). This DOT-technology combines simplicity and extraordinary clinical reliability with the possible identification of several autoantibodies in one single test. Together with a dedicated automated instrument, DIAsource Neptune, the diagnosis of auto-immune can be simplified and fully automated.
