Penny, R., Olambiwonnu, N. O., and Frasier, S. D.: Follicle stimulating hormone (FSH) and luteinizing hormone-human chorionic gonadotropin (LH-HCG) concentrations in paired maternal and cord sera. Pediatrics, 53:41, 1974.
An error was made by the authors under the Materials and Methods section of the above article which appeared in the January issue. The last two sentences should read:
To convert to nanograms of LER 907, multiply FSH concentrations by 24 and LH concentrations by 17. For conversion to International Units of commercial HCG, divide LH-HCG concentrations by 0.55.
