ABBOTT PARK, Ill., March 28, 2013 /PRNewswire/ -- Abbott (NYSE: ABT) today announced that the ARCHITECT AFP test, which may help doctors detect serious birth defects and the progression of testicular cancer, received U.S. Food and Drug Administration (FDA) approval. Biomarkers, such as alpha-fetoprotein (AFP), are substances in the body that physicians can measure to identify the progress of diseases or conditions as well as to evaluate the effectiveness of treatments. AFP has unique traits that help doctors detect two very different health issues: fetal birth defects and the progression of testicular cancer.
AFP and Birth Defects1, 2
Neural tube defects (NTDs) are serious fetal birth defects of the brain and spine that occur very early in development. When the neural tube, a structure that develops into the brain and spinal cord, fails to close properly, AFP is thought to leak directly from the fetus into the mother's amniotic fluid, causing unexpectedly high levels of AFP in the mother's blood. A blood test that measures AFP can help doctors determine if a woman is carrying a fetus affected with birth defects, such as anencephaly (the absence of a large part of the brain and the skull) and spina bifida (the incomplete closing of the backbone and spinal canal). Treatments for NTDs focus on closing the defect with surgery (including surgery before birth) and treating or addressing related symptoms such as excess fluid in the brain and bladder and bowel problems.
AFP and Testicular Cancer3, 4, 5
Men with one type of testicular cancer, called nonseminoma germ cell, have elevated AFP levels present in their bloodstreams. Blood tests to measure AFP can be used to evaluate responses to treatment. By monitoring disease progression and seeking treatment when necessary, testicular cancer can be a highly treatable and usually curable cancer.
"The ARCHITECT AFP assay is a valuable tool that will help physicians obtain reliable measurements of this protein for use in guiding critical patient treatment decisions," said Brian Blaser, executive vice president, Diagnostics Products, Abbott. "Abbott is pleased to offer this important assay to our customers to positively affect patient care."
About the ARCHITECT AFP Assay
The new assay runs on Abbott's fully-automated ARCHITECT i2000, i2000SR, ci8200, and ci16200 analyzers, and is available in the United States, CE marked, and non-regulated countries.
The ARCHITECT AFP assay is a chemiluminescent microparticle immunoassay (CMIA) for the quantitative determination of alpha-fetoprotein (AFP) in:
- Human serum or plasma to aid in monitoring disease progression during the course of disease and treatment of patients with nonseminomatous testicular cancer.
- Human serum, plasma, and amniotic fluid at 15 to 21 weeks gestation to aid in the detection of fetal open neural tube defects (NTD). Test results when used in conjunction with ultrasonography or amniography are a safe and effective aid in the detection of fetal open NTD.
