screening test for osteoporosis
Homework Answers
ANSWER.
* Screening test for osteoporosis.
* Dual energy X-ray absorptiometry (DEXA).
In this diagnostic test low dose X-ray beams
are used to detect bone mineral density.
* Quantitative CT scan.
In this test a computed tomography scanner is
used to obtain bone mineral density values.
this diagnostic test commonly used to evaluate
the mineral density of lumbar spine and hip.
* Quantitative Ultrasonography.
In this diagnostic test an ultrasound scanner is
used to detect bone mineral density of different
skeletal sites like phalanges,tibia,calcaneus etc
This test is commonly used for the assessment
of bone mineral density status of the children
due to lack of exposure to radiation.

A new screening test for colon cancer is developed. The screening test is evaluated by comparing results of 500 patient MRI results (in this case, considered the “gold standard” or confirming diagnostic tool). Of the 264 people who had a positive result on the new test, 211 were confirmed to have the disease by the MRI. Of the 236 people who had a negative result on the test, 97 were confirmed to have the disease by the MRI. Please calculate...

13. At a company, 75% of the employees pass a screening test to see if they need additional training. Of those that pass the screening test, 88% of them will be with the company at the end of one year. Of those who do not pass the screening test, 48% of them will be with the company at the end of one year. For the employees who will be with the company at the end of one year, % will...

A screening test for a specific disease is being evaluated. In order to evaluate the effectiveness of the new test, it is administered to 700 people in a given community. 120 of the individuals who had the disease tested positive and 80 tested negative on the screening test. A total of 50 people without disease tested positive. What is the predictive value positive of the screening test? 90% 60% 80% 71%

A prostate specific antigen
(PSA) test is a quick screening test for prostate cancer. A
researcher wants to evaluate it using two groups. Group A consists
of 1500 individuals who had biopsy-proven adenocarcinoma of the
prostrate while group B consists of 3000 age and race-matched
individuals all of whom showed no cancer at biopsy. The results of
the PSA screening test is each group is shown in the table below.

A study to determine the validity of a new screening test for Disease X is performed on 500 study subjects. The subjects also undergo a "gold standard" diagnostic test to definitely determine the presence or absence of the disease. The prevalence of Disease X among study subjects is determined to be 10% according to the gold standard. Of the 120 subjects who test positive with the screening test, 40 are determined to have the disease according to the gold standard....
