LH CLIA Test CE
The Luteinizing Hormone (LH) Chemiluminescence ImmunoAssay (CLIA) Test is a chemiluminescence-based immunoassay for the quantitative detection of LH in human serum or plasma (sodium heparin, K2EDTA, or K3EDTA) using the ALTA CLIAlyzer.
Luteinizing hormone (LH), also known as interstitial cell-stimulating hormone (ICSH), is a glycoprotein polypeptide hormone plays an important role in the regulation of normal growth, sexual development, and reproductive function.
LH stimulates secretion of sex steroid hormones from the gonads. In females, ovulation of mature ovarian follicles is induced by a spike in LH levels that is sometimes referred to as the “LH surge.” LH is also required for development and maintenance of the corpus luteum, which secretes estrogen and progesterone steroid hormones. In males, LH stimulates synthesis and secretion of testosterone by binding to its receptors on Leydig cells.
Abnormal LH levels have been found during aging, pregnancy, precocious puberty, menopause, castration, throughout hormone therapy, and in a variety of cases including primary ovarian insufficiency, primary testicular failure, polycystic ovarian syndrome (PCOS), Turner syndrome, multiple endocrine neoplasia, congenital adrenal hyperplasia, pituitary or adrenal tumors, thyroid disease, hypopituitarism, hypogonadism, eating disorders and organ failure.
Understanding optimal levels and accurate measurement of LH concentration and related hormones, therefore, is very important for both females and males. The LH CLIA Test is intended for testing in patients with any signs and symptoms of suboptimal LH levels, including issues with fertility, menstruation, and puberty.
Working range: 0.1-200 mIU/mL
Limit of Detection (LOD): 0.1 mIU/mL
CV less than 8%
CV less than 15%
Accuracy of ± 10% in comparison to the control
Linearity between 0.1 and 200 mIU/mL
No significant cross-reactivity was observed when TSH (100 μIU/mL), FSH (200 mIU/mL), or hCG (20,000 mIU/mL) were added to the LH Calibrator CAL 1, respectively. The results of LH in these samples were less than 0.1 mIU/mL.
No significant interference was detected up to the concentrations mentioned below:
|Total Protein||10 g/dL|
|Rheumatoid Factor||1000 IU/mL|
Patient specimens containing human anti-mouse antibodies (HAMA) may give falsely elevated or decreased values. Although HAMA-neutralizing agents are added, extremely high HAMA serum concentrations may occasionally affect the results.
There is no high-dose hook effect at LH concentration up to 1000 mIU/mL.
