Folic Acid (Definition)

Folic acid, AKA folate (folic acid) (vit B9), is recommended for all women wanting to get pregnant -- 0.4mg (400mcg) daily, which is important for preventing birth defects like spina bifida. Women w/ a hx these disorders should take 10x that amt daily -- 4mg (4000mcg) through the 3rd month of pregnancy. It won't affect fertility, chances of conception/twins, or periods. ...Read more

Ask your lab or MD: There is usually a within normal limits for the lab that you had them run by. You should go off of that. Also, a physician should discuss them with you and what to do about them if they are abnormal. Nothing is glaringly wrong if that helps. ...Read more

Perhaps: You are iron deficient either due to inadequate iron intake or poor absorption. You need additional iron in your diet through food sources and supplements. Add citrus to every meal containing iron to help with absorption. If you are not responding to supplemental iron you may be tested for sources of blood loss and/or inflammation affecting absorption. Consider gluten sensitivity. ...Read more

Had a blood test done (b12, folate, etc.) What does "tvit" stand for? Can't find it anywhere to see what it means to be low

Had a blood test done (b12, folate, etc.) What does "tvit" stand for? Can't find it anywhere to see what it means to be low

Tvit: Was there anything after it? Like B1 or D then it would stand for total vitamin B1 or total vitamin D You can always call your doctor or the lab and ask as well. ...Read more

What does it mean if both my B12 & Folates (folic acid) are low in one blood test but just B12 in repeat blood test?

What does it mean if both my B12 & Folates (folic acid) are low in one blood test but just B12 in repeat blood test?

Food supplements: Folate is added to many foods, e.g. cereals. If your folate level was marginally at the first reading, it may have been corrected though normal food intake. B12 absorption is more complex and may need injections to supplement. With the exception of B12 and vitamin D you do not need supplements if you are eating a mixed diet. And testing for "micronutrients" is a waste of money. ...Read more

Vitamin B 12 Level: I admire you for your concern for Health.
Normal values are 200 - 900 picograms per milliliter (pg/mL)
Some Labs may have higher range of Normal level.
High levels of vitamin B12 can occur in liver disease and some types of Leukemia, however vitamin B12 test is not usually used to diagnose these problems.

When I have complete blood count done, B12 and folate (folic acid) are a tad high, then when a separate blood test is done for B12 and folate (folic acid), both are ok. Causes?

Doesn't make sense.: If the same test done for the levels, and shows different results, there may also be a lab error. I would repeat one again only for b 12 and folate (folic acid) and compare. ...Read more

Hi, friend is getting a blood test soon (fbe, tsh, b12/folate and iron studies) him being a regular cannabis consumer, will the test detect marijuana?

Hi, friend is getting a blood test soon (fbe, tsh, b12/folate and iron studies) him being a regular cannabis consumer, will the test detect marijuana?

Unlikely: Thc metabolites are stored in body fats and excreted through urine. So it is unlikely that thc would be detected in blood test. But cannabis use would be detected in urine test. If he should be testers for employment etc., best he stop or reduce cannabis. Best regards, dr. Catherine shaw. ...Read more

What causes B12 deficiency? Blood test-B12=158, B6=2.4, folate=12.5, Homocysteine=12.9. I eat a balanced diet. On 325 of aspirin to prevent more DVTs.

Malabsorption: B12 is readily available in foods of animal origin (including dairy & eggs) so unless one is vegan you'll get enough via diet unless you can't absorb it; this can be caused by low hydrochloric acid, overgrowth of yeast or bacteria in the small intestines or a hereditary condition called pernicious anemia.Take methylcobalamin orally or by injection.

How can one tell the difference between low b12 and pernicious anaemia? Mildly low ferritin, b12, folate (folic acid) and red blood cells. Hair loss too.

How can one tell the difference between low b12 and pernicious anaemia? Mildly low ferritin, b12, folate (folic acid) and red blood cells. Hair loss too.

This is serious: Pernicious anemia is one cause of a low B12 but your situation is complicated. If you are a non-supplementing vegetarian, please reconsider. You will need a proper set of labs and an inquiry as to the cause of each deficiency. Insist on full explanations ...Read more

Microcytic anemia: Iron deficiency causes a "microcytic anemia", meaning the red blood cells are smaller (measure by the mean corpuscular volume or MCV). If there is simultaneously a macrocytic anemia, which can be caused by low folate or low B12, then the average MCV could be normal but there would be both smaller and larger cells (and the spread of cell sizes, measured by the RDW would go up). ...Read more

Why is my blood test level of Ferritin 375.9? What causes that?

Why is my blood test level of Ferritin 375.9? What causes that?

Many possible causes: This means that there may be excess iron in your body. Find out the normal values for your laboratory? This differs depending on the laboratory doing the test.

If your ferritin is actually elevated, taking iron supplements may be a cause. Liver disease or a disorder called hemochromatosis can also elevate the ferritin. Speak with your doctor. ...Read more

Hi I am a woman of 29 years. Yesterday I picked up the results of a blood test. My ferritin levels are above the reference range for women. 298 ng / mL. I get iron 12.20 umol / L. In february, ferritin was normal, 61ng/mL. Why? Its dangerous? Thanks.

Not to worry: In some labs that would be a normal range. Low ferritin means you're low on iron. Since you been getting iron treatment your new ferritin level probably indicates it's time to back off or slow down. Hi ferritin can be from inflammation or too much iron or if it's chronic hemachromatosis. Which since you've had low iron wouldn't be the case. Good health ...Read more

How much does ferritin increase with each prbc transfused? How long does the increase take to show in blood test?

How much does ferritin increase with each prbc transfused? How long does the increase take to show in blood test?

Not much: Studies shown 14 days out no change or minimal change. The reason is that when u get blood transfusion u are requiring blood to be used immediately for your organs, so the iron that is connected to the hemoglobin in the red blood cell needs to be used on demand and not really stored in ferritin form. This is with iron deficiency anemia or chronic blood loss anemia. Different than chronic dis anem ...Read more

My blood test results are: Hgb 10.8 Mcv 77.4 Serum ferritin 6 Can you tell me what these mean and if I should be concerned?

Anemia: The low hemoglobin indicates that you have anemia and the other two values suggest that this is due to insufficient iron. Most often in a woman of your age this is due to menstrual blood loss. Iron supplementation or a higher iron content in your diet should allow you to recover and feel better. ...Read more

Very serious: Vegetarianism is moral high ground but if you do not supplement scientifically, you will ruin your health. You are a young woman and need iron. Your physician will recommend something based on a full work up. Please use discernment in evaluating "pop" claims about health and lifestyle. ...Read more

Can you please tell me what it means from my Iron Studies blood test - when my Ferritin levels are low 25 (Ref 30-300) and my Sat is high 63 (10-45)?

Repeat the tests: Any evidence of iron deficiency is very serious especially at your age even if you're not anemic. You need to be screened for GI / GU bleeding, have your diet reviewed (if you are a vegetarian, please reconsider), and have a history. There may also be a lab error. High serum Fe / sat can happen if you take a few iron pills before seeing the doctor "for your health". ...Read more

You're anemic.: This is serious business. You need to work with your physician to discover the reason. Get all the iron studies together, including total iron binding capacity, along with your personal history, and a report on how your peripheral smear looks, and perhaps a reticulocyte count. Don't stop until you understand why and what you can do to perhaps save your life. ...Read more

Blood test shows ferritin level of 541. Rbc of 3.6 and hg of 12. Being treated for anemia. High ferritin concerns me. Need help to understand.?

Blood letting: A high ferritin is bad news because it catalyzes free oxygen radicles. They can be compared to sparks jumping out of a fire in the process known as oxidation, or fuel burning to provide cellular energy. The essential treatment is blood letting until the ferritin gets into the normal range, it is the only use of therapeutic blood letting. ...Read more

Ferritin (Definition)

Ferritin is protein complex that binds iron and controls iron levels inside all of our cells. Low levels in the serum is a useful marker of iron deficiency. Macrophages are cells that contain large amounts of ferritin, and this that helps them scavenge RBC at sites of old hemorrhage. High serum ferritin levels occurs from macrophage activation and is a ...Read more
