	Drug sensitivity tests for tubercle bacilli (Site not responding. Last check: 2007-11-06)
		Sensitivity tests are designed with the object of detecting such a decrease in sensitivity.
		The best approach is to compare the sensitivity of a sample of strains from untreated patients (a predominantly sensitive sample) with a sample of strains from patients who have been treated with the drug for atleast a few months (a predominantly resistant sample).
		To avoid misclassification of sensitive strains as resistant, it is preferable to choose a sensitive strain, although it may occasionally fail to detect strains with border-line degrees of resistance.

		Formally, a sensitivity test is a test that determines how great a change occurs in the value of an output variable with a change in the value of either an input variable or a parameter intrinsic to the model.
		Sensitivity tests can be grouped into two types: intrinsic sensitivity, which is sensitivity to parameter estimation, and external sensitivity, which is sensitivity to input or external variables, such as air temperature and precipitation.
		Sensitivity to the maximum and not to the minimum degree-day parameter is due to the location of the Superior National Forest relative to the range of balsam fir, which as I explained earlier (and which should be apparent from discussions in previous chapters), is near the southern boundary of the geographic distribution of balsam fir.

	Chemo-sensitivity and resistance testing
		Chemosensitivity testing is an attempt to do something similar for cancer; fresh samples of the patient's tumor from surgery or a biopsy are grown in test tubes and tested with various drugs.
		Sensitivity implies that when a patient's cancer cells are treated with a particular chemotherapy agent in the laboratory, that agent will kill the cancer cells or inhibit their proliferation.
		The goal of all chemosensitivity tests is to determine the response of a patient's cancer cells to proposed chemotherapy agents.

	Environmental Health Perspectives 105, Supplement 2, March 1997: Cognitive and Psychomotor Performance Tests and ...
		Performance tests generally are not standardized; they are almost always adapted to improve their sensitivity for the purposes for which they are used.
		However, determining whether a score is normal or abnormal depends on the sensitivity and reliability of the test in discriminating between normal and abnormal individuals, and on the reliability and validity of the norms.
		Tests based on factor analysis and resource models are phenomenological in that they represent and often resemble skills and behavioral phenomena that humans exhibit in real life.

		A second sensitivity test was performed whereby the temperature at level B+ was recomputed in a similar manner (see the lower left panel).
		Finally, another test was performed where the term containing the jump in the longwave radiative flux across the PBL top was removed from the entrainment rate formula.

	2002 Laboratory Guidelines - 3
		Test sensitivity is emphasized to minimize occurrence of false-negative tests, which can result in complications of untreated infection and ongoing transmission.
		The sensitivity of non-NAATs with urine or vaginal swab specimens is suboptimal.
		Additional tests will be required to differentiate between species that might produce acid from glucose but not from maltose, sucrose, or lactose (Appendix F) or to identify variant gonococcal isolates that fail to produce acid from glucose.

		The sensitivity of the nonamplified hybridization test (71.6%) was similar to that reported in an earlier study (75.3%) that compared the hybridization test, three EIAs, and a DFA performed on endocervical swab specimens by using culture as the reference standard (79).
		For endocervical swab specimens, the sensitivity of LCR (85.5%) exceeded that of culture (74.7%) by 10.8% and that of the hybridization test (61.9%) by 23.6%.
		For the urine specimen, the sensitivity of LCR was 80.8%.

	Optometric Management: Using Contrast Sensitivity to Assess Quality of Vision (Site not responding. Last check: 2007-11-06)
		In general, contrast sensitivity tests are divided according to two criteria: Stimulus type and lighting conditions.
		Early contrast sensitivity tests, most of which were printed, were difficult to compare and interpret due to a lack of standardized lighting.
		For example, letter contrast sensitivity tests are most appropriate for patients with low vision or in research settings, where patients' responses cover a very wide range.

	Analysis of Sensitivity Tests
		Sensitivity tests are often used to estimate the parameters associated with latent continuous variables which cannot be measured.
		For example, in testing the sensitivity of explosives to shock, each specimen is assumed to have a critical stress level or threshold.
		Sensitivity tests sometimes result in tests with no overlap because of limited sample size or an inefficient test design due to faulty initial estimates of the parameters.

		New testing technologies such as contrast sensitivity, contrast acuity and ETDRS acuity are being more widely used to measure the quality of vision related to eye care treatments.
		This is particularly important now that new surgical techniques have excelled to a level where many patients attain 20/20 or better standard visual acuity.

		Another key consideration in network sensitivity tests is the logical location of a WAN segment.

	Pregnancy Test - Sensitivity Comparision
		The pregnancy tests on the market today range widely in their sensitivity in picking up the pregnancy hormone, hCG.
		Your period arriving is a sign that you are not pregnant this cycle, as is a negative blood test from your doctor.
		If you use a very sensitive pregnancy test, where you test before the day your period is due, you could catch an early pregnancy but end up going on to have your period anyway due to a very early miscarriage.

		The best times to test are between 11am and 3pm and 5pm and 10pm.
		If you want to make sure that you catch your LH surge, you may want to test twice a day, once in the earlier time frame and the other in the later time frame.
		Please keep in mind that while you may have the initial surge of LH earlier in the day if testing via blood tests, you will not get a positive result on the ovulation test until 4-5 hours later when the surge actually reaches your urine.
