Question 1

what does intrinsic factor mean?

Accepted Answer

Gastric receptor B12: It is a glycoprotein produced by the parietal cells of the stomach. There are many cell types in the stomach, but the parietal cell makes this factor. It is necessary for the absorption of vitamin b12, which occurs in the small intestines. If you don't absorb b12, you can develop macrocytic anemia.

Question 2

can you replace intrinsic factor?

Accepted Answer

Intrinsic Factor: The main issue with intrinsic factor is that it helps with absorption of B12 (a vitamin) and a low B12 level will eventually effect your red blood cells. The optimal way to prevent this in those with intrinsic factor depletion is to supplement their B12 intake with injections that bypass the GI tract. If this is a condition you are suffering from, you would benefit from seeing a GI specialist soon.

Question 3

what is the difference between intrinsic and extrinsic cardiomyopathy?

Accepted Answer

The cause: A cardiomyopathy is a term indicating a weak heart with impaired function. Your question is using a different nomenclature than used by cardiologists. Cardiomyopathy are classified as systolic dysfunction with low ejection fraction. Diastolic dysfxn with a preserved ejection fraction but a stiff heart. They can be idiopathic with unknown cause, ischemic with CAD or caused by other diseases

Question 4

what is the definition or description of: intrinsic factor blocking ab?

Accepted Answer

Leads to B12 defic: Pernicious anemia is a chronic illness caused by impaired absorption of vitamin b-12 because of a lack of intrinsic factor (if) in gastric secretions. It occurs as a relatively common adult form of anemia that is associated with gastric atrophy and a loss of if production and as a rare congenital autosomal recessive form in which if production is lacking without gastric atrophy.

Question 5

what causes b12 levels drop rapidly in may it was 100 after injections in june 600 again today its 140 how sudden drop m waiting for reports of intrinsic factor?

Accepted Answer

Vitamin B 12 : My guess is that your body has been putting the injection to use. The level in June was  because of the injection, but, your body processed and stored that supply, and you probably just need a few more injections. B12 is a micro nutrient, you don't need much of it, and once your stores are complete, your level should stay normal four months to years.

Question 6

b-12 intrinsic antibody blocking test is negative, i eat lots of meat so why is my b-12 low?

Accepted Answer

Many possibilities: A single lowball value may be a lab error. If you're just below the reference range, remember it's set so that several percent of healthies fall outside on either end. Mild malabsorption from whatever cause, salivary or pancreatic insufficiency, a bit of terminal ileitis or something else in the distal ileum, or an antibody of your own that interferes with your assay. Glad it was detected.

Question 7

what does " metal artifact causes mild intrinsic cord heterogeneity comprising detection of small non-expansile cord lesion"?

Accepted Answer

Artifact: Artifact in medicine denotes a substance that is not naturally present. In your MRI a fragment of metal obscured a portion of the image of the spinal cord making for an indeterminate conclusion about a possible lesion.

Question 8

when does the intrinsic factor return back again after gastric sleeve. and can i get vit b12 from pills after gastric sleeve by 1 year?

Accepted Answer

: The best way to objectify: obtain blood tests for Vit B-12 and MMA about every 3-4 months, but in the meantime, follow your doctor's advice.

Question 9

i got my intrinsic factor antibody test back as equivocal. how long should i wait before retesting to see if its positive or negative?

i will ask my gi but am looking for other opinions please. thank you?

Accepted Answer

: You may not need to repeat the same test. Wait for the GI Doctor’s opinion because he may want to send a different test, like a Parietal Cell antibody Test, that is a bit less specific but helps to confirm Pernicious Anemia. Plus, we don’t know if the lab ran both IF Antibodies (Blocking and Binding). Your GI will know. Just be sure not to use bit B12 at least 2-3 wks before if they retest you.

Question 10

what doesthis mean
small wedge shaped intrinsically t1 hyper intense area adjacent to the falciform ligament likely represents a perfusion abnormality?

Accepted Answer

?liver: I assume you're reading a report from an abdominal MRI describing an abnormality seen in the liver (?) but there's not enough information to comment.
