    • Cytokine
    • General clinical chemistry
  • Available Assays

    Show All

    The Clinical Translational Research Center Biochemistry Core Laboratory at Children’s Hospital Medical Center provides clinical and research assays for the study bone and mineral metabolism disorders:

    Calcitropic hormones and Vitamin D 

    Parathyroid hormone and vitamin D 25-OH are measured using chemiluminescence immunoassay (CLIA) methodology. 1, 25 dihydroxy vitamin D is measured by a competitive equilibrium radioimmunoassay (RIA).

    Minerals

    Total calcium and phosphorus are measured on an automated analyzer (cobas c 311) using second generation chemistry methods.

    Biochemical Markers of Bone Turnover

    The assorted formation and resorption markers (BALP,PICP, CICP, ICTP, NTx, PYD) are measured using ELISA methodologies.

    Nutritional Status Assays

    The laboratory provides clinical and research assays for assessment of nutritional status:
    Carnitine (total, free, and short chain) is measured using a radio-enzymatic assay. Prealbumin levels are measured using an automated chemistry analyzer. Vitamins A and E are measured using HPLC methodology.

    Endocrine Assays

    The laboratory provides many research assays for the assessment of endocrine health.
    The various hormone levels (ACTH, Cortisol, DHEAS, estradiol, FSH, LH, progesterone 17-OH, testosterone and TSH) can be measured by CLIA, ELISA, or RIA. Obesity related assays such as adiponectin, ghrelin, leptin, and PYY are measured by ELISA.

    Cytokine Assays

    The laboratory currently uses ELISA methodologies for all human cytokine analyses.

    General Clinical Chemistry Assays

    The laboratory provides research assays for many general chemistries using a cobas c 311 automated analyzer. Assays available include lipid profiles, renal function, total bile acids, glucose, C-reactive protein as well as others listed in the Comprehensive Test Menu. Tests not listed but commercially available for the analyzers can be discussed with the laboratory supervisor.

    The following assays are available to investigators through the Clinical Translational Research Center Biochemistry Core Laboratory at Cincinnati Children’s Hospital Medical Center. Details of the assay methods and measuring ranges can be obtained by contacting  the laboratory supervisor.

  • Custom Test Development

    If you don't see the test you're looking for, you can request the development of a new test. Contact us with the requested test and the CTRC Scientific Advisory Committee will review the request. Preference will be given to analyses used by more than one investigator and likely to be used by multiple investigators in the future.
