Links and Definitions


Information gathering. "Knowing is half the battle." -G.I. JOE

This page will continue to be a work in progress as I add more information. I will link what I find relevant to my diagnosis and situation. Since this is meant both for myself and as a shared resource I am willing to add something specific upon accepted request.





ANAs : are a group of antibodies that react against normal components of a cell nucleus. About 70% of Sjögren's patients have a positive ANA test result. This antibody test is indicative of a rheumatic disease, including rheumatoid arthritis (RA), lupus and Sjögren's.​

Anti-Ro/SSA and La/SSB antibodies : are the most prevalent specificity among many autoimmune diseases.

A positive ANA : test result means that autoantibodies are present. In a person with signs and symptoms, this suggests the presence of an autoimmune disease, but further evaluation is required to assist in making a final diagnosis.

Antineutrophil cytoplasmic antibodies (ANCA) : are autoantibodies produced by a person's immune system that mistakenly target and attack proteins within the person's neutrophils (a type of white blood cell).

Creatinine : is filtered from the blood by the kidneys and released into the urine, blood levels are usually a good indicator of how well the kidneys are working.


Ferritin : is a blood cell protein that contains iron. A ferritin test helps your doctor understand how much iron your body is storing.

Folate : is one of the B-vitamins and is needed to make red and white blood cells in the bone marrow, convert carbohydrates into energy, and produce DNA and RNA.

Glomerular filtration rate (GFR) : is a measure of the function of the kidneys.

Hematocrit : test measures how much of your blood is made up of red blood cells.

Hemoglobin (Hb or Hgb) : is a protein in red blood cells that carries oxygen throughout the body. A low hemoglobin count is only slightly lower than normal and doesn't affect how you feel. If it gets more severe and causes symptoms, your low hemoglobin count may indicate you have anemia.

LDL-CHOLESTEROL : tests for low-density lipoprotein cholesterol (LDL-C) is used as part of a lipid profile to predict an individual's risk of developing heart disease and to help make decisions about what treatment may be needed if there is borderline or high risk.

Low iron values : in conjunction with elevated TIBC values (or specifically measured transferrin concentrations), yielding less than 16 percent transferrin saturation, generally indicate iron-deficiency anemia (World Health Organization 2001). Transferrin saturation values in excess of 60 percent may be indicative of hemochromatosis or iron overload (World Health Organization 2001). 

Total iron binding capacity (TIBC) : is a blood test to see if you have too much or too little iron in your blood. Iron moves through the blood attached to a protein called transferrin. This test helps your health care provider know how well that protein can carry iron in your blood.

MCH (mean corpuscular hemoglobin) : refers to the average quantity of hemoglobin present in a single red blood cell.

MCHC (mean corpuscular hemoglobin concentration) : test is a standard part of the complete blood count (CBC) that is done during blood analysis, and the value is used to evaluate the severity and cause of anemia.

MCV (mean corpuscular volume) : measures the average red blood cell volume, meaning the actual size of the cells themselves.

MPO : is a peroxidase enzyme that in humans is encoded by the MPO gene on chromosome 17. MPO is most abundantly expressed in neutrophil granulocytes (a subtype of white blood cells), and produces hypohalous acids to carry out their antimicrobial activity.

NON HDL CHOLESTEROL : measuring your non-HDL cholesterol levels gives a better assessment of the risk for heart disease than measuring only LDL. This is especially true if you have high triglycerides.

RDW : blood test is often part of a complete blood count (CBC), a test that measures many different components of your blood, including red cells. The RDW test is commonly used to diagnose anemia.

Triglycerides : test measures the amount of triglycerides in your blood.

Urea Nitrogen, Blood (BUN) :  test measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is made when protein is broken down in your body. Urea is made in the liver and passed out of your body in the urine. A BUN test is done to see how well your kidneys are working.
