Usually utilization category is mentioned in most of the switch gear, with the above contactor stating to be used under AC1 - resistive load & AC3 for motor usage. In electrical engineering utilization categories are defined by IEC standards [1] and indicate the type of electrical load and duty cycle of the loads to ease selection of contactors ...
The triple test, also called triple screen, the Kettering test or the Bart's test, is an investigation performed during pregnancy in the second trimester to classify a patient as either high-risk or low-risk for chromosomal abnormalities (and neural tube defects). The term "multiple-marker screening test" is sometimes used instead.

By comparison, in the same 4000 women, a screening test that has a 99% sensitivity and a 0.5% false positive rate would detect all 10 positives while telling 20 normal women that they are positive. Therefore, 30 women would undergo a confirmatory invasive procedure and 10 of them (33%) would be confirmed as positive and 20 would be told that ...
All cancer screening tests generate both false-positive and false-negative results, with a tendency to yield more false positives. [10] False-negative tests may provide a false sense of reassurance, possibly leading to a bad prognosis if the cancer is diagnosed at a later stage, despite the utilization of surgeries, therapies, and other treatments.
For example, the ColoGuard test may be used to screen people over 55 years old for colorectal cancer. [57] Cancer is a longtime-scale disease with various progression steps, molecular diagnostics tools can be used for prognosis of cancer progression. For example, the OncoType Dx test by Genomic Health can estimate risk of breast cancer.
Of all women with HSIL results, 2% [8] or less [9] have invasive cervical cancer at that time, however about 20% would progress to having invasive cervical cancer without treatment. [ 10 ] [ needs update ] To combat this progression, HSIL is usually followed by an immediate colposcopy with biopsy to sample or remove the dysplastic tissue.
The majority of hospitals in the UK have implemented rapid-access breast cancer screening clinics where the triple test score is used as a clinical diagnostic tool. [ 25 ] [ 26 ] Ongoing research efforts are essential for the long-term effectiveness and applicability of the triple test score in healthcare settings.
