Rbc lo. Hgb, hct ok. Mch & MCV hi. Ferritin ok. B12 & folic acid hi. D lo. Thyroid ok. Rf hi. Repeatable. Tired, weak and unfocused. Cause?

Additional info: What are the actual number values associated with the rbc, hgb, hct, mch, and mcv? This will help establish significance of these high or low values. Do you have relatives with RA or other autoimmune disease? Do you have any history of hepatitis or liver disease (can cause simultaneous high rf and high mcv)? Are there other lab test results for autoimmune disease (ana)? ...Read more

Unintentional weight loss. Low iron levels low b12 and folate (folic acid). Can't get answers.?

Unintentional weight loss. Low iron levels low b12 and folate (folic acid). Can't get answers.?

Wt loss, low iron: Could be from a vast number of possibilities. This question requires more information. A good history, physical exam and scrutiny of current, past and future bloodwork will all help piece together this puzzle. In general low iron in healthy premenopausal women is usually from menstruation or pregnancy. The weight loss is somewhat worrisome. Highly recommend a formal consultation with a doctor. ...Read more

My body is low in B12 and folic acid. I was given national nasal spray 500 mcg. What other fruits and vegetables can I use to bring up these two thing?

My body is low in B12 and folic acid. I was given national nasal spray 500 mcg. What other fruits and vegetables can I use to bring up these two thing?

Green leafy!: Green leafy vegetables are great sources of folic acid. Beans and other sources are shown here: http://www. Veganhealth. Org/b12/folate there are no reliable vegetarian sources of b12--it is made by bacteria and supplements are the most reliable way. If you have trouble with absorption, your doctor can provide a B12 shot. ...Read more

If you are anemic but have normal B12 and folate (folic acid), (folic acid) could there be another nutrient related to folate (folic acid) or to B12 that is low?

If you are anemic but have normal B12 and folate (folic acid), (folic acid) could there be another nutrient related to folate (folic acid) or to B12 that is low?

Well, sure: Iron deficiency is the most frequent cause of anemia. If you have already been checked for that, your provider needs to look at several other things not necessarily related to nutrition to determine the cause. Don't just take iron, though, unless your tests show that it is deficient. ...Read more

My vitamin B12 level was 292. Is this too low? I was deficient in folate (folic acid) and my homocysteine level was 13.5.

My vitamin B12 level was 292. Is this too low? I was deficient in folate (folic acid) and my homocysteine level was 13.5.

Folate (folic acid) dieficiency: Would be uncommon in an 18 yo. A B12 level between 200 and 400 can be difficult to interpret. Under 200 clearly low and over 400 likely ok. In between is a grey area. ...Read more

When both folate (folic acid) and B12 are low, which should you start to take first, and why?

When both folate (folic acid) and B12 are low, which should you start to take first, and why?

B-12 first: Treating a B-12 deficient patient with folate (folic acid) may correct the anemia, but not stop the progression of irreversible nerve damage. It masks the B12 deficiency, in other words. ...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?

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

Is a folate (folic acid) level of 10 a normal level? Does is it matter if my B12 level is low (276)? My homocysteine is 12.

See below: Your folate (folic acid) level is normal. However, one needs B12 for folate (folic acid) to work properly. Depending on the reason for low B12 you may need to take it by injection. See this site for more info on folate (folic acid).

My serum folate (folic acid) is 16.4ug/L & B12 is 221ug/L & serum ferritin is 22ug/L. Why is folate (folic acid) on the high end of normal & others on the low end of normal?

Nothing to worry abt: These are all in the normal range, and there is some give and take regarding the laboratory ability to give an exact value. Don't worry about these values unless they are way higher or way lower than normal. ...Read more

Folate (folic acid) 53/B12 1500/Both 1.5-2xUNL. Are these levels good for pregnancy? I know low levels link to risks of birth defects. What about high levels?

Folate (folic acid) 53/B12 1500/Both 1.5-2xUNL. Are these levels good for pregnancy? I know low levels link to risks of birth defects. What about high levels?

Needs further eval: If you are reporting the usual units for folate (folic acid) and B12, then they are high. The most likely explanation is that you are taking these in supplements anticipating pregnancy. If so, you are taking too much and should cut back to only recommended intake. If you are not taking supplements or medications, this needs prompt evaluation as it could be related to liver, kidney or bone marrow problems. ...Read more

Hi I started rec B12 injec recently. Felt much better however Tues I fainted. My r cell folate (folic acid) was 346 before injs could this be low off inj?

Utility of B12: The proven utility of B12 injections for symptoms of fatigue, listlessness, general malaise is an age old debate. It certainly has its role in certain pathologies such as neuropathies, dementia, and certain forms of anemia. In general, I look for other reasons to explain all the things people think B12 cures which have never been proven. B12 would not LOWER your folate (folic acid) levels anywhere in the body ...Read more

HB 126, Low MCV, low MCH, high WBC, high neutrophils, ferritin 45 (was 13), folate (folic acid) 5.9, B12 high from treating B12 def. Any ideas on what's wrong?

Wrong approach: Forgive my frankness. Labs are only useful as adjuncts to the history and physical exam. You need a relationship with a competent physician. You're only 25 but you say you have osteoporosis. You were B12 deficient -- why? If you've been a non-supplementing vegetarian, it's very dangerous. Recovering iron deficiency? Thal minor? How high are the neuts? Any immature / strange ones? Your Dr must ansr ...Read more

8 wks post-op gastric sleeve surgery. Down 70#'s Blood work came back w/low hematocrit, hemoglobin & mpv were low. Folate (folic acid) & B12 were norm What's wrong?

8 wks post-op gastric sleeve surgery. Down 70#'s Blood work came back w/low hematocrit, hemoglobin & mpv were low. Folate (folic acid) & B12 were norm What's wrong?

Post op anemia: Most likely is a reflection of some blood loos during the surgery, which is not unusual. It takes around 3 months for your blood levels to normalize. At this point it is very unlikely that your anemia is due to some sort of vitamin deficiency. I would not worry about. Just continue taking your vitamin supplements. And follow up labs in a few months. ...Read more

Have hbp take lisinopril, B12 deficiency monthly injection, and low folace take folic acid. Woke up this morning with a black eye, no trauma why?

Have hbp take lisinopril, B12 deficiency monthly injection, and low folace take folic acid. Woke up this morning with a black eye, no trauma why?

Black eye: A black eye is typically a result of trauma or contusion with leaking of blood from superficial capillary vessels. Lisinopril can cause a kind of skin reaction called 'angioedema' which involves mostly swelling, but could turn dark if rubbed a lot. B12 won't due nor folic acid. Vitamin c deficiency would predispose. Most likely it is due to incidental mild contusion, perhaps while you slept. ...Read more

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

Nausea and diarrhoea coincides with monthly cycle. Some numbness in face and hands. I have low B12 and folate (folic acid). Dr just diagnoses ibs. Any idea?

Maybe: The hormone shifts at the time of menstruation often give women some temporary bloating, diarrhea and cramping pain. It can be treated as ibs, some women use spironolactone or birth control pills to reduce symptoms. Ginger or chamomille teas can also help with the cramping. ...Read more

Enlarged glands in neck, collarbones, armpits, groin, for 3 yrs no infection but slight raised protein in blood recentand folate (folic acid) low, im 26, is it lymphoma?

Enlarged glands in neck, collarbones, armpits, groin, for 3 yrs no infection but slight raised protein in blood recentand folate (folic acid) low, im 26, is it lymphoma?

Unlikely: Watch them to see if they increase in size. As long as the size of the nodes is smaller than 1.5cm, I would not consider it to be a lymphoma. But if they grow in size up to 2 cm, then a biopsy should be considered. That is the final proof as to what is the cause for their enlargement. ...Read more

Inositol: Inositol is a vitamin-like substance. It is found in many plants and animals. It can also be made in a laboratory.

Inositol is used for diabetic nerve pain, panic disorder, high cholesterol, insomnia, cancer, depression, schizophrenia, Alzheimer’s disease, attention deficit-hyperactivity disorder (ADHD), autism, promoting hair growth, a skin disorder called psoriasis, and treating side effects of medical treatment with lithium.

Inositol is also used by mouth for treating conditions associated with polycystic ovary syndrome, including failure to ovulate; high blood pressure; high triglycerides; and high levels of testosterone.
Do you need it pre-pregnancy - probably not. ...Read more
