Ovarian Cancer Monitoring Test

HE4 assay uses a simple blood test
The ARCHITECT HE4 assay from Abbott Diagnostics, Abbott Park, Ill, helps monitor the recurrence or AbbottHE4progression of ovarian cancer. The HE4 (human epididymis protein 4) assay uses a simple blood test to aid in monitoring for the recurrence or progression of this disease. The current test most widely used to monitor ovarian cancer, CA125, measures levels of a protein in the blood as an indication of a possible recurrence of disease progression in ovarian cancer patients. While 80% of ovarian cancers express CA125, 20% of all ovarian cancers do not. By using this test in conjunction with other clinical methods, including CA125, physicians can get a more comprehensive clinical picture when monitoring ovarian cancer patients.

New Testosterone Test to Measure the Hormone at Low Levels
Helps diagnose related conditions in women
The ARCHITECT 2nd Generation Testosterone assay from Abbott Diagnostics, Abbott Park, Ill, which runs on Abbott’s fully automated ARCHITECT family of analyzers (model i2000SR pictured), helps Abbott i2000s_copyphysicians accurately measure the wide range of testosterone levels seen in both women and men. It is a chemiluminescent microparticle immunoassay for the quantitative determination of testosterone in human serum and plasma. Measurement of testosterone plays an important part in the diagnosis of many conditions, and it can guide treatment decisions. Levels are associated with sexual development, libido, protection against osteoporosis, and cardiovascular health. Polycystic ovary syndrome (PCOS) is a common endocrine disorder that can result in excessive production of testosterone, leading to infertility, irregular or absent menstrual periods, and hirsutism (excess body and facial hair). Inappropriate testosterone levels can also result in precocious or delayed puberty.
