It is an interesting fact that the globulin levels in the blood are directly linked with the levels of albumin in your body. This is the primary reason that any blood test used to identify the level of one substance requires the doctor to gauge the level of the other substances as well. Both substances are considered to be a prime indicator of the nutritional status of the body.
A globulin blood test is very often called for when attempting to screen the body when diagnosing conditions like liver disease, kidney disease and other conditions that are detected with routine testing. It is also important to point out that elevated globulin levels in the blood could also be nothing more than a consequence of dehydration - which can be easily remedied by increasing the patient's intake of fluids and water.
As with most other types of blood tests, blood tests for globulin will require you to lie down on an examination table at the doctor's clinic. Your arm will be prepped in order to obtain a sample of your blood. The area on the arm, just behind the elbow, will be cleansed with some antiseptic lotion and a tight band may be fastened towards the top of the arm in order to temporarily restrict blood flow. This will cause the vein in the arm to bulge and allow the presiding doctor or nurse greater accuracy when attempting to puncture the vein. Once the syringe has been injected into the vein, a sample of the blood will be collected in an attached vial and the syringe withdrawn. A piece of cotton is then pressed over the site of the puncture to avoid any unnecessary bleeding. The vial containing the blood sample will then be sealed, marked and sent to the laboratory for analysis where the level of globulin in the blood will be tested.
There is no specific preparation required when undergoing a globulin in blood test. However, it is important that you inform your doctor of any medication that you may be taking, prescribed or otherwise, as there may be a tendency for these substances to interfere with the final readings of the blood test. There are no severe risk factors associated with the blood test but one must make sure that the syringe used in a new one to prevent the possibility of being affected by HIV. Some patients may also need to be a little careful about excessive bleeding.
