Blood Tests - What and Why

As many of you may know, I am project managing my cancer and its treatment. Part of that includes my Education Plan - providing information that is helpful to me and may be helpful to others in similar circumstances. One of the key things I am doing to try to feel like I have some control is log all of my blood work. I will not show you my actual results - that's taking being open a bit too far, even for me - but I will show you what they test for, what the ranges are, and what the results can show.

This is what my doctor is looking at when ordering blood tests. I hope you find it educational:

Lab Range Notes
(BUN/Creatinine ratio) 6.0 - 22.0 Kidney: Usually between 10:1 and 20:1; increased ratio could indicate congestive heart failure or dehydration. One to watch.
(GFR African American, estimated) N/A Kidney: If below 60, talk to Doc; can be a sign of kidney damage 
(GFR non-African American, estimated) N/A Kidney: If below 60, talk to Doc; can be a sign of kidney damage 
Alanine aminotransferase measurement (ALT/SGPT) 6.0 - 29.0 Liver: High levels can indicate liver disease
Albumin measurement (Albumin) 3.6 - 5.1 Made in Liver: Helps keep fluid in your bloodstream; carries hormones, vitamins, enzymes. If low, could indicate malnutrition
Albumin/Globulin ratio (A/G ratio) 1.0 - 2.5 Test the protein in your blood; can help diagnosis kidney and liver disorders; 
Alkaline phosphatase measurement (Alkaline phosphatase) 33.0 - 130.0 Shows signs of liver disease or bone disorder; if low, could be due to a deficiency of zinc or malnution
Aspartate aminotransferase measurement (AST/SGOT) 10.0 - 35.0 Tests for liver disease; if ST levels are low, your liver is damaged.
Basophil count (BA #) 0 - 0.2 High level of basophil can be a sign of chronic inflammation; or it could mean something is causing too many white blood cells in marrow
Basophil, percent (BA %) 0 - 1.0 Healthy range is from 0 to 3; log level can be caused by infections, severe allergies or an overactive thyroid gland
Bicarbonate measurement (CO2) 20.0 - 32.0 Tests how much CO2 levels are in your blood; too litte or too much could be signs of liver failure, kidney disease, or anorexia.
Bilirubin, total measurement (Bilirubin, total) 0.2 - 1.2 Liver: red blood cells in the liver; Elevation can indicate liver disfunction
CA 15-3 measurement <30 U/ml Cancer antigen; Assists in determining disease recurrence after treatment of metastaic breast cancer
CA 27-29 measurement <38 U/m; Cancer antigen; Predicts early recurrenct of women treated for breast cancer.
Calcium measurement (Calcium) 8.6 - 10.4 Tests calcium levels in the blood; required for blood clotting and crucial for density and maintenance of bones and teeth
Carcinoembryonic antigen measurement (CEA) <2.5 ng/ml - <5 ng/ml Cancer Marker; measures a protein called CEA in blood
Chloride measurement (Chloride) 98.0 - 110.0 Measures chloride electrolytes; helps maintain proper blood volume, blood pressure, and PH of body fluids; high could = dehydration
Creatinine measurement, serum (Creatinine) 0.5 - 0.99 Measures how well your kidneys are filtering; 5.0 or more could indicate severl kidney impairment
Eosinophil count (EO #) 0 - 0.3 Special white blood celss that curb infection and boost inflammation; if high can indicate parasite infection, allergic reaction, or cancer
Eosinophil, percent (EO %) 0 - 3.0 Disease fighting white blood cell; normal range is between 30 and 350; destroys invading germs.
Globulin measurement (Globulin) 1.9 - 3.7 Test proteins in the blood; if levels are low, can mean you have liver or kidney disease
Glucose measurement (Glucose) 65.0 - 99.0 Measuring glucose levels; normal is less than 140 mg/dl 2 hours after eating
Granulocytes, immature, automated (IG #) 0 - 0.03 Early stage response to infection; high = infection, autoimmune disease, blood cancers; low - 
Granulocytes, immature, automated, % (IG %) 0 - 0.5 Predicts severe bacterial infection; determine infected vs non-infected persons
Hematocrit determination (HCT) 37.0 - 47.0 % of red blood cells in the blood; igh = lung or heart disease; low = fatigue, weakness, izziness, shortness of breath; cold hands/feet
Hemoglobin determination (HGB) 12.0 - 16.0 Helps red blood cells transport oxygen from your lungs: High = smoker or high attitude; low = anemia
Lymphocyte count (LY #) 1.2 - 3.4 Type of white blood cell; if high, evidence of infection, cancer of the blood or lymphatic system; low = greater risk of infection, cancer
Lymphocyte, percent (LY %) 15.0 - 41.0 A type of white blood cell; high = fighting infection or inflammation; low = significant illness
Mean corpuscular hemoglobin concentration determination (MCHC) 33.0 - 37.0 How much hemoglobin is inside a red blod cell; low = not enough; anemia; high = red blood cell destruction or fragility
Mean corpuscular hemoglobin determination (MCH) 27.0 - 31.0 Mean corpusal hemoglobin; low = iron deficiency anemia; high = deficiency due to B vitamines, specifically B-12
Mean corpuscular volume (MCV) 81.0 - 99.0 Mean corpusal volumn; elevated level related to increased risk of liver cancer, aging, nutrition; survival prediction in chronically ill
Monocyte count (MO #) 0 - 1.0 White blood cells in tissues; low = chemo; high could = lymphoma
Monocyte, percent (MO %) 3.0 - 11.0 % is the number of white blood cells that move out of circulating and into tissues; low = chemo, bone marrow failure; high = leukemia
MPV 7.4 - 10.4 Platelet volumn; average size of platelets found in your body; if high, bone marrow inclreasing output  re: old platelets beind destroyed.
Neutrophil count (Neu # (ANC) 1.5 - 6.5 Absolute white blood cell count; changes can be caused by chemo, radiation, infection, surgery, or anxiety
Neutrophil, percent (Neu %) 40.0 - 77.0 Type of white blood cell; makes up 70%; produced in the bone marrow; high counts indicated infection
Platelet count (PLT) 130.0 - 400.0 Platelets circulate within the blood and bind together when they recognoize damaged blood vessels; stops us from bleeding
Potassium measurement (Potassium) 3.5 - 5.3 Measures potassium levels needed for proper muscle and nerve function; increases/decreases can indicate health issues
Protein measurement (Total protein) 6.1 - 8.1 Measures total protein; if high, could indicated your body is fighting infection or other inflammation
Red blood cell count (RBC) 4.2 - 5.4 Normal not pregnant women is 4.2 to 5.4; if too high, could indicate heart failure, low blood ozygen and other heart disease.
Red cell distribution width determination (RDW) 10.5 - 14.5 Measures the amount of red blood cell various in volumn and size; High RDW means nutrient deficiency, anemia or other condition
Sodium measurement (Sodium) 135.0 - 146.0 Measures sodium; if too high or too low, could indicate kidney issues, dehydration or other medical conditions.
Urea nitrogen measurement (BUN) 7.0 - 25.0 Measures the amount of protein broken down in the body; If high, can indicate heart failure, dehydration or high protein diet
White blood cell count (WBC) 4.8 - 10.8 Determines your bodies ability to fight infection; less than 4.0 to 4.5 means your body cannot fight infection
