What Is A Spiromtetry Test
Complex study: A pulm stress test or cpx is a very thorough study were the performance of the lung (function) is being measure while at work (exercise). But also ther cardiac function & its interaction with the resp system are measure in a very exact way. Full pulmonary function parameters are measure & a total oxygen capacity seen at its perfect application. Done in athletes & patients as well. Very exact stud. ...Read more
Depends: As noted there are many different tests and these are usually combined in a "battery" that attempt not only to measure the degree and severity of brain abnormalities, but also try to predict how individuals will function given the injuries, deficits, or degrees of decline. The tests are also used to track the progression of a disease, and plan rehabilitation treatments and programs. ...Read moreSee 2 more doctor answers
Different: A pregnancy test and an ovulation predictor test have some similarities, but are quite different. The ovulation predictor test will detect the hormone signal triggering an egg to release from the ovary. Several over-the-counter test kits are available: you test your urine once daily during the time of the month you may be ovulating. Your pharmacist can help you choose an appropriate kit. ...Read more
Cardiac testing: There are lots of 'good tests', we choose by what we need to know. ECG gives us general rate, rhythm and some other info. Echocardiography shows anatomy, physiology and some other info. Nuclear imaging can show anatomy, some physiology and other info. Radiographic angiograpy is very important for coronary anatomy. There are plenty of other 'good tests' too. ...Read more
Checks lung function: Pfts check numerous areas of lung capacity, flow rates, etc. And are useful in treating/diagnosing emphysema, copd, restrictive ariway diseases, asthma, and understanding lung capabilites prior to surgery. This would be common in smokers, elderly, or in patients with lung diseases like cystic fibrosis. Pfts are easy and done in a lab or pulmonary specialist's facility. ...Read more
Autonomic nerv syst: The qsart test is used in neurology to measure the nerves that control sweating. It is helping in determining if there are any abnormalities with the autonomic nervous system (i.e. Heart, bp, GI tract). It is also useful in determining a problem with the small nerve fibers, which can be abnormal in disorders such as complex regional pain syndrome. ...Read more
HbA1c: It depends on lab normals. Mostly less than 6 percent. Now many define less than 5.7 percent as completely normal. ...Read more
If below your peers: An abnormal result on a pft (pulmonary function test) depends on one's value compared to his/her age-matched peers. Standard pft's are divided into 3 sections, the first spirometry (which measures exhalation efforts), the second lung volumes, and the third "diffusion capacity( ability of oxygen to transfer into lung's blood vessels).". ...Read more
Determines Pregnancy: Urine pregnancy tests are available at pharmacies, grocery & convenience stores. They can be done in the privacy of your home. All pregnancy tests are based upon measurement of the hormone -- human chorionic gonadotrophin or HCG -- which is made after a fertilized egg implants in the uterus. Pregnancy can be determined as early as the first day of the missed period with 97%-99% accuracy. ...Read moreSee 1 more doctor answer
PFT's: are tests that look at your lung function. They are used to tell if you have obstructive disease by looking at how much air you can blow out; they can tell if you have a restrictive disease by looking at your lung volumes; and they can tell how well you are able to exchange oxygen between your alveoli (air sacs) and capillaries by doing a diffusion test. ...Read moreSee 1 more doctor answer
