HCG, Quant



Human chorionic gonadotropin (hCG) is a glycoprotein hormone, produced by the placenta, with structural similarity to the pituitary hormones FSH, TSH, and LH. The alpha subunit (MW 15,000-20,000 daltons) is common to all of these hormones but the beta subunits differ, and confer immunological and biological specificity. Beta hCG (MW 25,000-30,000 daltons) shares several peptide sequences with beta LH, but has a unique carboxyl terminal region

Transport Tube

Invert the tube gently no more than eight times. Further inversion may cause alterations in sample integrity.
Do not remove the stopper at any time. Do not centrifuge immediately after drawing blood. Allow the blood to clot in an upright position for at least 30 minutes but not longer than 1 hour before centrifugation. Centrifuge for at least 15 minutes at 2200-2500 RPM within one hour of collection. Label the tube with the patient’s last name, patient’s first name, date of birth, date of collection, time of collection.
