What different types of blood tests are there
A CBC with differential looks at the amounts of different types of white blood cells in your blood. Typical clinical blood panels include a basic metabolic panel or a complete blood count. Rheumatoid factor is actually an antibody that can bind to other antibodies.
However, infections, stress, and exercise will temporarily raise the white blood cell count, too.
A CBC also measures hemoglobina component of red cells that contains iron and carries oxygen. The hematocrit is the percent of total blood volume that is made up of red cells. A lower hematocrit can be caused by a number of factors or conditions, including RA.
Erythrocyte sedimentation rate — The erythrocyte sedimentation rate ESR is a test in which a blood sample is placed in a tube to see how far the red blood cells settle in one hour.
10 Common Types of Blood Tests to Consider
Inflammation in the body produces proteins in the blood, which make the red cells clump together and causes them to fall faster than the healthy blood cells. Also included in the Chemistry Panel is an assessment of critical minerals such as calcium, potassium, and iron. An important contributor to blood clotting, fibrinogen levels increase in response to tissue inflammation. Since the development of atherosclerosis and heart disease are essentially inflammatory processes, increased fibrinogen levels can help predict the risk of heart disease and stroke.
High fibrinogen levels not only are associated with an increased risk of heart attack, but also are seen in other inflammatory disorders such as rheumatoid arthritis and glomerulonephritis inflammation of the kidney. In a recently published study from the University of Hong Kong Medical Center, researchers identified increased levels of fibrinogen in the blood as an independent risk factor for mortality in patients with peripheral arterial disease. When left untreated, peripheral arterial disease increases the risk of heart attack, stroke, and death.
This study followed men and women with peripheral arterial disease for an average of six years.
The 10 Most Important Blood Tests
Death from all causes increased with elevated fibrinogen levels: Researchers concluded that increased fibrinogen was an independent risk factor for mortality in this patient population.
In the February issue of the Journal of Thrombosis and Haemostasis, researchers reported an association between increased levels of fibrinogen and risk for venous thrombosis blood clots. A combination of lifestyle and behavioral changes—such as quitting smoking, losing weight, and becoming more physically active—may help to lower fibrinogen levels to the optimal range. These tests usually are done on the fluid plasma part of blood. The tests can give doctors information about your muscles including the heartbones, and organs, such as the kidneys and liver.
The BMP includes blood glucose, calcium, and electrolyte tests, as well as blood tests that measure kidney function. Some of these tests require you to fast not eat any food before the test, and others don't. Your doctor will tell you how to prepare for the test s you're having. Glucose is a type of sugar that the body uses for energy.
Arthritis & Blood Tests
Abnormal glucose levels in your blood may be a sign of diabetes. For some blood glucose tests, you have to fast before your blood is drawn. Other blood glucose tests are done after a meal or at any time with no preparation. Calcium is an important mineral in the body.
Abnormal calcium levels in the blood may be a sign of kidney problems, bone disease, thyroid disease, cancer, malnutrition, or another disorder. Electrolytes are minerals that help maintain fluid levels and acid-base balance in the body. They include sodium, potassium, bicarbonate, and chloride. Abnormal electrolyte levels may be a sign of dehydration, kidney disease, liver disease, heart failurehigh blood pressureor other disorders. Blood tests for kidney function measure levels of blood urea nitrogen BUN and creatinine kre-AT-ih-neen.
Both of these are waste products that the kidneys filter out of the body. Abnormal BUN and creatinine levels may be signs of a kidney disease or disorder. Enzymes are chemicals that help control chemical reactions in your body. RF Rheumatoid factor A protein produced in an aggressive form of juvenile idiopathic arthritis. Also present in some people without arthritis. TFT Thyroid function Measures activity of the thyroid gland. A-Z of blood tests by investigation. Clinical services Research Our consultants Referrals.

The blood levels of these proteins help monitor reaction of the liver to a medication or to a viral infection or inflammation of the liver caused by lupus or another inflammatory disease. A protein produced in many forms of inflammation. In arthritis, a high level indicates an increased risk of developing eye inflammation.
Patients with SLE will have high levels, but this is not a diagnostic test.
