What is a Lab Test?
A lab test can be anything from blood, urine, hair, DNA (cheek swab) or other things. It depends on what is being tested. First the sample is obtained by a qualified technician, nurse or physician, then your job is done! Depending on the test you may have to return to the office for it to be read (like a TB test where they prick your skin then read the prick a few days later). Often though they don’t need you physically there and they can do the test and simply send you the results.
Why Get a Lab Test

- drug testing for employment

- verify immunity or the presence of a disease like TB
For the patient, a lab test typically consists of the lab obtaining the sample. Generally, you don’t need to be there during the actual testing. They will take the sample, whether blood, hair, urine, saliva, etc., then you will be allowed to go and they will send the results. For things like a blood sample, a needle is involved. Some tests are slightly different like a TB test where they prick your skin, then you must return after a day or so and they will “read” the test and verify the result.
If you are going for a blood test, short sleeves are preferred over long, tight sleeves.
You can have a CT scan done in a hospital or an outpatient facility. CT scans are painless and, with newer machines, take only a few minutes. The whole procedure typically takes about 30 minutes.
During the procedure
CT scanners are shaped like a large doughnut standing on its side. You lie on a narrow, motorized table that slides through the opening into a tunnel. Straps and pillows may be used to help you stay in position. During a head scan, the table may be fitted with a special cradle that holds your head still.
While the table moves you into the scanner, detectors and the X-ray tube rotate around you. Each rotation yields several images of thin slices of your body. You may hear buzzing and whirring noises.
A technologist in a separate room can see and hear you. You will be able to communicate with the technologist via intercom. The technologist may ask you to hold your breath at certain points to avoid blurring the images.
After the procedure
After the exam you can return to your normal routine. If you were given contrast material, you may receive special instructions. In some cases, you may be asked to wait for a short time before leaving to ensure that you feel well after the exam. After the scan, you’ll likely be told to drink lots of fluids to help your kidneys remove the contrast material from your body.
