Laboratory Testing

A TSH blood draw typically goes into a lavender or purple-top tube containing an EDTA anticoagulant. This tube is used for testing thyroid-stimulating hormone (TSH) levels as part of thyroid function tests.

green top tubes are used for blood culture and cd4 and cd8 count etc.

The answers to this section in chapter 13 on mutations is not available online. The answers must be gathered by rereading the chapter in the book.

s.g. is the density of a substance as compared to that of the density of water which is 1.000.s.g. of a solution depends on the amount of solute present and also on the temp. of the solution.the s.g. increases with increasing conc. of the solute.

the s.g. of normal urine is 1.003 to 1.030.if the kidney is functioning properly, the concentrated first morning sample of urine should have a s.g.greater than a.020.

usually, increased discharge of urine accompanied by decrease s.g.is typical of diabetes insipidus. on the other hand, high volume of urine discharged with increased s.g. suggests glucosuriya, associated with diabetes mellitus, or proteinuria.

if the conc. power of the kidney is disturbed, there is a combination of low s.g. and low volume of urine discharged. this occurs in case of glomerulonephritis and pyelonephritis.

two methods are employed in measuring the s.g., urinometer method and refractometer method.

The Modified Barium Swallow test seeks to show the individual's swallowing pattern and any swallowing problems the patient is experiencing.

- No patient preparation is necessary before the test. You can eat and drink normally.

- The total study takes about 10 minutes, with 5 minutes of fluoroscope imaging.

- Patient is seated or standing.

- The patient consumes a small variety of items containing barium, including thin liquid, thick liquid, semi-solid (pudding), solid (cookie) and a barium tablet.

- The study is video-recorded for later play-back and analysis.

- The testing is done by a Radiologist and a Speech Pathologist (expert in Swallowing Disorders.)

- It evaluates swallowing, including oral cavity, pharynx, larynx and cervical esophagus.

- It detects the presence of aspiration (getting food in the air tube) and the causes.

- If the patient aspirates (inhales food), therapy is provided to help control it.

After the examination, you can resume your usual diet and take your usual medications unless told otherwise by your doctor.

For a day or two your bowel movements may look white because of the barium.

Sometimes the barium can cause temporary constipation, which can be treated by an ordinary laxative.

Drinking more fluids for several days following the test can also help.

no need to fast for these tests.

Yes, a doctor can test your urine for various purposes, such as checking for urinary tract infections, kidney function, or drug screenings. The results from a urine test can provide valuable information about your overall health.

Do your own search. Hah take that. Now you are just reading and wasting your time and you couldn't do anything about it. :)

Upper GI series

both are normal

It rather depends on why blood is being drawn?

residual volume specimen

A fasting blood glucose of 137 is a concern. A random blood glucose of 137 is not a concern.

need not

A red-top tube is typically used for the RPR (Rapid Plasma Reagin) test, as it does not contain any additives that can interfere with the test results.

Glucose studies use gray top tubes. The additive in grey tubes prevent glycolysis. Lactic acid test also uses a gray top.

Yes, fasting is not required for an HDK1 CD57 blood panel. This test is typically used for identifying patients with Lyme disease or other chronic infections and does not require fasting before the sample collection.

There is no recommended amount of creatine to take before an ETG test to mask the presence of alcohol. It is not advisable to try to manipulate the results of a drug test as it can have serious consequences. It is best to abstain from alcohol to ensure accurate test results.

The blood lipid profile is a group of tests that measure the levels of different types of lipids (fats) in the blood. It typically includes measurements of total cholesterol, LDL (low-density lipoprotein) cholesterol, HDL (high-density lipoprotein) cholesterol, and triglycerides. This profile helps assess a person's risk for cardiovascular diseases.
