Cdt test - Doctor answers
How long of abstinence from alcohol will give a normal CDT test level. I need this to regain my driving licence?
NinetyDaysToFreedom: The half-life of Carbohydrate-Deficient Transferrin (CDT, the substance tested in the CDT Test) is on average 17 days. And it takes about 5 half-lives to get near zero, assuming you stopped all alcohol intake. A half- life is the time for the amount to halve (duh).So 5X17=85 days so round up to 90 days or three months. Suggestion, at that point you'll be well on your way to having stopped drinking! ...Read moreSee 1 more doctor answer
Halo, I had a medical done for work, after a long weekend (have been drinking that weekend) and they found my GAMMA GT is 100. They want to send me for a CDT test. So except for keeping away from alcohol, what else can I do, to help? I will be doing the C
No alcohol problem. Had blood tests done 2days after an evening out. So want to know how to get the level in blood down before CDT test?
CDT is not likely to be abnormal from drinking one day. It is a marker for chronic alcohol use. If you have been drinking over the past two weeks, CDT may be abnormal and there is not way for you to affect the results now. Alcohol never did any body any good, so stay away from it. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.

Took a early cdt lung test at pcp office. He orders for all patients didn't ask for it. Out of 6 test on the cdt mage4 was a little ovr cutoff. Cancer?
Evaluate risks: I may be outdated but I don't do the same. The test is too nonspecific for diagnosis or even to establish risk that I don't do it. Look at your risks, get a cxr or if needed a low rad ct. The cdt misses too many with actual cancer, i.e., can be negative and there is cancer, and can be positive when there is none. In my opinion, it only causes more anxiety and sometimes rift between md and patient. ...Read moreSee 1 more doctor answer
Recently my doctor order an early cdt lung test as part of annual blood work that he screens. When the results were returned, is was positive for one?
Asses risk: I just answered another one like this. The problem with the cdt is that a negative test is most likely negative when correlated with imaging. A positive test can be present in patients with negative imaging and it can be negative in people with positive imaging. The importance of the test right now is still unclear. Low radiation ct is better in people stratified by risk and symptoms. ...Read moreSee 1 more doctor answer
Today I received a pos result for a Early CDT Lung Test. In April 15 I had neg CT, Dec 15 I had neg CXR. Should I have another CT. Ongoing fatigue.
Early CDT: With out a nodule being present on a CT Chest, Early CDT has essentially no meaning. (not endorsed or recommended by any society) At 49 years of age, u would not have been a candidate for CT screening unless u have some other history that would compel ur Doctor to screen with either modality. I would have urself evaluated by Lung specialist to gather more info and gage ur risk. Good luck ...Read more

I took the eatly cdt lung cancer test. They were all negative except the mage4. Ct was clear. Does this mean I have cancer elsewhere? Or it is to come
Unclear: Not sure why test was performed. The data of this test/technology is still preliminary. Antibody biochemical assays may identify the presence of tumor/cancer years before they are large enough to find by radiology; therefore before we can actually treat. If used, results should be integrated into overall risk assessment, screening, surveillance. Test should not be routinely employed without a plan. ...Read more
If u had a early cdt lung blood test and out of six tests the mage4 was a little over cutoff and u are ANA positive 1:640 spec. Suggest cancer?
Autoimmune: I can't say much about the earlycdt test- it is not primetime at this time. To me, the test has to go through validity and quality control first and there is no a good clinical trial that backed up this test- I won't use it at this time. If you don't know how to interprete the result-it only creates anxiety &unnecessary test. You may have autoimmune disease-especially if you have symptoms. D/w md. ...Read more
Had a early cdt lung blood test only one that was just barely elevated was the mage4. I have also had chest CT scan that was normal. This means what?
Were they: Looking for a blood clot, or pulmonary embolus, in the lung? If so the ct scan should rule it out but wait for better advise! I'm not sure what a cdt lung blood test is nor the mage 4 but that was probably the screening test to get the ct which was negative. Wait for a better opinion but the ct, i'll bet, ruled it out. I'm gonna try to refer you to a genius pulmonary guy in my online network. ...Read more
Nov 12 I had a early cdt lung cancer test. Only mage4 was slightly elevated. Ct was clear then. Twomonths ago clear chest xray. Could this b cancer?
If you tested positive for mage4 on a early cdt lung blood test and have +ana 1:640 and elevated sed. Clear chest CT and MRI spine ok. Cancer?
Check with your doc:
Mage4 on a early cdt lung blood test was ordered by a doc, although you do not seem to be a high risk patient and you probably do not smoke 3 packs daily. Therefore the test was not necessary and now we have false positive result.
You may have some form of lupus, or sle, or something else. I highly doubt that you have cancer. However, check with your doc to be safe. Ask why the test was necessary. ...Read more

Should I be concerned about a positive mage a 4 test? Mage= melenoma antigen gene? I had early cdt lung cancer blood test. Ct of lungs clear
MAGE A4 Tesring: The mage a4 antigen, even though it was named the melanoma associated antigen, is a non-specific antigen that has been linked to a wide variety of tumors. It's efficacy is still being debated as a stand alone predictor. Your physician should investigate and rule out the most likely malignancies for your age and family history, including early breast and oral cancer, as well as others less likely. ...Read moreSee 1 more doctor answer
Upper back pain since last may. Dr ordered CT of chest. It was clear. Also took early cdt lung cancer blood test the magea4 was positive. Worry?
What for?: Mage a4 is not an approved screening test for lung cancer, was this done as part of a research trial? Lung cancer in a 39 year old with a clean ct chest would be very unusual, and in a person with very low risk of cancer any screening test that is positive is most likely a false positive. I would suggest discussing the purpose of the test and results with the doctor who ordered it! ...Read moreSee 1 more doctor answer
