Hoping you can tell me, is level of 8 on a CEA blood test highly elevated?

CEA test: Carcinoembryonic antigen test is to detect response to therapy in cancer patients, especially colon cancer, with normal range of less than 2.5 (less than 5 in heavy smokers). Note that a positive test may not always be indicative of cancer. Review with your doctor. ...Read more

Blood test reveals a CEA level of 7.6ug/l. Never had cancer that i know of. I am a smoker 50yrs of age, female?

Blood test reveals a CEA level of 7.6ug/l. Never had cancer that i know of. I am a smoker 50yrs of age, female?

Don't screen w/CEA: Cea (carcinoembryonic antigen) is not meant to be used as a screening test for cancer as many cancers don't produce it and smoking can raise the value, leading to unwarranted worry and further invasive testing to dispel said worry. Check out http://labtestsonline.Org/understanding/analytes/cea/tab/test for more info, especially it's proper use & role. ...Read more

Cea blood test levels low but cat scans show more cancer?

Possible: Please note that CEA is just another tool we have and as such it is not perfect. Many patients have elevated CEA and have no cancer and many others have clinical and x-ray evidence of active cancer and yet their CEA is normal. Such tumors just don't produce CEA and in those cases, the test is useless. No test is infallible. ...Read more

I'm 33 - smoker - family history of cancer - Had blood test all normal but CEA 5.4 - creatinine 0.6 - monocytes 9% . Could I have cancer?

I'm 33 - smoker - family history of cancer - Had blood test all normal but CEA 5.4 - creatinine 0.6 - monocytes 9% . Could I have cancer?

Why were you tested?: CEA is a poor screening test in people without symptoms or signs of cancer. And reference ranges are set so that a few percent of healthy folks fall outside on either end. This is very slightly above reference range and not uncommon for a smoker. Please try to stop and ask your physician whether chest imaging and/or colonoscopy are in order. ...Read more

A friend has been told they have colon cancer, diagnosed via a tumour marker blood test, high cea, CT scan showed contained mass. Is this conclusive?

A friend has been told they have colon cancer, diagnosed via a tumour marker blood test, high cea, CT scan showed contained mass. Is this conclusive?

No, but...: But very suspicious for colon cancer. If your friend is similar in age to yourself a mass in the colon on ct scan is cancer until proven otherwise. And CEA levels can go up for other reasons but, given the mass, they would strongly favor cancer. But to answer your question "no"... They are not definitive. You would need a piece of the mass under a microscope to prove definitively its cancer. ...Read more

I am a breast cancer survival - do I need to do the tumour markers blood test -ca153, ca19.9, ca12.5, cea, afp?

I am a breast cancer survival - do I need to do the tumour markers blood test -ca153, ca19.9, ca12.5, cea, afp?

Generally no: Standards of care in the us do not recommend routine tumor marker testing in cancer survivors (we usually do ca 27.29 for breast cancer). Markers are mostly useful to assess response to therapy in patients with advanced cancer. That said, many oncologists (myself included) will sometimes order routine markers in cancer survivors depending on the circumstances. ...Read more

Recent blood test showed my bun at 18 and my creative at 1.02 both on high end of range, should I be worried ?

No: If you are a muscular male, these results would be right in the normal range. As it is the results are within normal limits. However, all lab results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. See this site for more info.

It depends: A one time blood glc reading means nothing. Is there a fam hx of diabetes, are you overweight, how do you feel, do you have certain symptoms, (increased urination, thirst, fatigue after meals), what are gluc reads at other times, are your periods regular? These and more all have meaning. Was a HbA1c test done, this is a 3 month avg of your gluc and can categ you: nl, inc DM risk, borderline or DM ...Read more

Eosinophils: Eosinophils are a type of white blood cell that typically increase with allergy or inflammation. The fact that you have ulcerative colitis tells me you have an inflammatory condition going on in your body. The elevated eosinophils could indicate that your disorder may not be in full remission or may be in an early flare-up stage. Talk over with GI doc. ...Read more

Few years ago I felt in a blood test report that the bilirubin was slightly above the normal range. In a latest test it is 1.9 mg/dl. Pls comment.

Few years ago I felt in a blood test report that the bilirubin was slightly above the normal range. In a latest test it is 1.9 mg/dl. Pls comment.

I'm not worried: Several percent of humankind have Gilbert's, a non-disease with somewhat elevated bilirubin. If you've skipped a few meals in a row and noticed your eyes got a bit yellow when viewed in sunlight, that's you. Or you might be tearing up red blood cells from a mild hemoglobin problem or from exercise. If you seem healthy otherwise, don't worry about it. ...Read more

Hi. I had my blood test recently and the iron level came with the range of 2. What does that mean? Can this cause me a further problems? Any concern?

Clarify: Is this a serum iron level substantially below the reference range? Are you also anemic? Is your total iron binding capacity up? If you are iron deficient, you must demand to know why. Are you a non-supplementing vegetarian? Do you have heavy menstrual losses? Have you been checked for a bleeding ulcer / possible cancer? The situation is VERY serious and you need to be proactive & informed. ...Read more

Had blood test it was out of range what does it mean?

Had blood test it was out of range what does it mean?

It means you can...: Visit the doctor ordering the blood test to ask whether or not "out-of-range" is normal for you; and if not normal, what should be done about it. Out-of-range means a higher or lower number than 95% of a group of normal people's lab results. In other words, if you check 101 "normal people", about 95 will have results in-range, 3 will be lower than in-range, and 3 will be higher than in-range. ...Read more

What does a result of <10 for a rheumatoid factor blood test? Normal range for the test was 0-13.9

RF: Well it could mean nothing because a lot of healthy people have positive RF, also it just could be an active phase reactant which increases in setting of stress, inflammation or infection. So having said that we should know why it has been checked? I don't see any joint pain or swelling in your history. ...Read more

My homocysteine level was 15. Blood test said it was high bc range went up to 12. Is a 15 dangerous?

No: Not dangerous, just one of many risk factors for developing coronary disease at a later time. Try to improve the risk factors you can with a healthy diet, not smoking, knowing you cholesterol, and treating if needed, and maintaining a healthy weight. Do not smoke! Homocysteine levels can be lowered with certain b vitamins, but the benefit of this treatment is uncertain. ...Read more

Histamine blood test was 101, it says reference range is 180-1800. Is my result low and does it mean anything?

Histamine blood test was 101, it says reference range is 180-1800. Is my result low and does it mean anything?

Ignore it: "Histamine blood test" is at the borderland of scientific medicine. Whether "histamine intolerance" is a real / common entity (I suspect it is) and whether the best test is a spot lab (I don't know) are questions that I will let others answer decisively. It's hard to study. I would not be at all concerned if you're below a reference range here -- this is just what MOST people have. ...Read more

Its not: I believe that the test is wrong. If your Po2 was 32 you would be very short of breath, have blue lips and finger nails and not feel well at all. this sample was either from a vein or an aberrant lab result. It should be repeated. ...Read more

My ESR value is 51 and im experiencing lots of body pain. I did 3 blood test and the ESR ranges at 62..48..51...What does this suggest?

ESR: This is a non-specific indicator of infection. The things that elevated the rate at which red blood cells will sediment are an increase in globulins (due to tumors or infection or other), and increase in fibrinogen, a substance released from the liver under stimulation by fibrin degradation products. The reasons for you to have high esrs must be assessed by a clinician in context with illness. ...Read more

Reference range value of homo-cysteine blood test report is 8-20 mg/dl. Does anyone know about any similar or same reference range value? Thank you.

Reference range value of homo-cysteine blood test report is 8-20 mg/dl. Does anyone know about any similar or same reference range value? Thank you.

Ranges vary: Reference ranges for homocysteine vary some from lab to lab. Most physicians today set little by this number, as an atherosclerosis risk or otherwise, unless it is very far above the upper limit you've cited. Of your many listed problems, the one that concerns me is papilledema / blurry vision; i'm concerned you have pseudotumor cerebri and this vitamin ; lab test stuff diverts the investigation. ...Read more
