Genomic testing is becoming increasingly common in medicine. Moreover, ongoing advances in technology and an ever-increasing understanding of what genetic variants mean can result in reinterpretation of the clinical significance of variants found in patients. This can occur when the patient’s indications for the original test are unchanged or when their phentoypes or family histories […]Continue Reading ...
What is an SHBG blood test? This test measures the levels of SHBG in your blood. SHBG stands for sex hormone binding globulin. It’s a protein made by the liver and attaches itself to sex hormones found in both men and women. These hormones are: Testosterone, the main sex hormone in men Dihydrotestosterone (DHT), another […]Continue Reading ...
Findings could lead to early diagnosis, better treatment studies An ultrasensitive test has been developed that detects a corrupted protein associated with Alzheimer’s disease and chronic traumatic encephalopathy (CTE), a condition found in athletes, military veterans, and others with a history of repetitive brain trauma. This advance could lead to early diagnosis of these conditions […]Continue Reading ...
A new test for cervical cancer was found to detect all of the cancers in a randomized clinical screening trial of 15,744 women, outperforming both the current Pap smear and human papillomavirus (HPV) test at a reduced cost, according to a study led by Queen Mary University of London. The study, published in the International […]Continue Reading ...
Multigene tests have been used in breast cancer treatment to assess the risk of metastasis for several years. A team at the Breast Cancer Center at the Technical University of Munich’s (TUM) Klinikum rechts der Isar has now presented results based on data collected in its routine clinical work. These results show that the multigene […]Continue Reading ...
Australian researchers have found that cells containing cancer could soon be detected using a simple test. The test could one day change how cancers are diagnosed, the team says. The results of the study to develop the test were published in the journal Nature Communications. Cancer cells in their early stages have certain DNA signatures, […]Continue Reading ...
Stressful events in the evening release less of the body’s stress hormones than those that happen in the morning, suggesting possible vulnerability to stress in the evening. The body’s central system reacts less strongly to acute psychological stress in the evening than it does in the morning, according to research conducted at Japan’s Hokkaido University. […]Continue Reading ...
What is a karyotype test? A karyotype test looks at the size, shape, and number of your chromosomes. Chromosomes are the parts of your cells that contain your genes. Genes are parts of DNA passed down from your mother and father. They carry information that determines your unique traits, such as height and eye color. […]Continue Reading ...
What is a thyroglobulin test? This test measures the level of thyroglobulin in your blood. Thyroglobulin is a protein made by cells in the thyroid. The thyroid is a small, butterfly-shaped gland located near the throat. A thyroglobulin test is mostly used as a tumor marker test to help guide thyroid cancer treatment. Tumor markers, […]Continue Reading ...
Researchers at the Queen Mary University of London have developed a new cervical cancer test that proved to be 100% effective at detecting the cancer in a trial of 15,744 participants. Komsan Loonproom | Shutterstock The study demonstrated that the epigenetics-based test outperformed both the Pap smear and the human papilloma virus (HPV) test, as […]Continue Reading ...
What is a PTT (partial thromboplastin time) test? A partial thromboplastin time (PTT) test measures the time it takes for a blood clot to form. Normally, when you get a cut or injury that causes bleeding, proteins in your blood called coagulation factors work together to form a blood clot. The clot stops you from […]Continue Reading ...
Today, the only way to definitively diagnose Alzheimer’s disease in life is through brain scans and tests of cerebrospinal fluid that must be collected via lumbar puncture. Though cumbersome and expensive, such tests provide the most accurate diagnoses for patients. Investigators at Brigham and Women’s Hospital are working to develop a blood test that could […]Continue Reading ...
Credit: CC0 Public Domain An international team that includes Rutgers scientists has made significant progress in developing a urine diagnostic test that can quickly, easily and inexpensively identify tuberculosis infection in people also infected with HIV. TB is the leading infectious disease killer in the world and the most common cause of death for people […]Continue Reading ...
What is a gonorrhea test? Gonorrhea is one of the most common sexually transmitted diseases (STDs). It is a bacterial infection spread through vaginal, oral, or anal sex with an infected person. It can also be spread from a pregnant woman to her baby during childbirth. Gonorrhea can infect both men and women. It is […]Continue Reading ...
What is a pregnancy test? A pregnancy test can tell whether you are pregnant by checking for a particular hormone in your urine or blood. The hormone is called human chorionic gonadotropin (HCG). HCG is made in a woman’s placenta after a fertilized egg implants in the uterus. It is normally made only during pregnancy. […]Continue Reading ...
