Neonatal Genetic Metabolic Disease
Tandem mass spectrometry (MS) for the detection of genetic metabolic diseases with the advantages of high sensitivity, high specificity, high select�ivity and rapid detection

Reproductive Health

    Inborn errors of metabolism (IEMs) are a group of diseases that result from a genetic defect in an enzyme, receptor, transport protein or membrane pump which is essential to maintain the normal metabolism of the body. They have a wide variety, high overall incidence, complex and varied clinical manifestations, and the lack of specificity. If not timely diagnosis and treatment, often disabling, even life-threatening.

Product introduction



    Newborn screening is to detect the levels of amino acids, free carnitine and acyl carnitine in dried blood spots from a heel stick by liquid chromatography-tandem mass spectrometry (LC-MSMS). It's sensitive, specific, selective and fast. We can detect 48 common IEMs including disorders of amino acid, disorders of organic acid and disorders of fatty acid in one test by LC-MSMS, with the efficiency of newborn screening greatly improved.
