False negative results may occur when the levels of hCG are below the sensitivity level of the test. Diluted urine specimens with low specific gravity may not contain enough hCG for detection. If pregnancy is still suspected, a first morning specimen should be obtained. A number of conditions other than pregnancy, including trophoblastic disease, and certain nontrophoblastic neoplams; including testicular tumors, prostate tumors, breast cancer and lung cancer cause elevated level of hCG. This test reliably detects intact hCG up to 5000,000 mIU/mL. It does not reliably detect hCG degradation products, including free-beta hCG and beta core fragments. Quantitative assays used to detect hCG may detect hCG degradation products and therefore may disagree with the results of this rapid test. This test provides a presumptive diagnosis for pregnancy. A confirmed pregnancy diagnosis should only be made by a physician after all clinical and laboratory findings have been evaluated.
