Can either blood or urine be used for the MMA test?
In most cases, it is okay to use blood or urine for this test. Sometimes, your doctor may want to test both your blood and urine in order to compare the MMA results. Since homocysteine is a blood test, it may be more efficient to draw blood for both the MMA and homocysteine tests when they are ordered together.

A study was made to assess the value of cobalamin deficiency detection through quantitation of urinary methylmalonic acid (MMA). Urinary MMA was measured in 1118 patients suffering from megaloblastic anemia, other anemias, elevated red cell mean corpuscular volume, or unexplained neurologic disorders. Patients without proven cobalamin deficiency had urinary MMA levels less than 20 micrograms/ml. All patients (n = 27) confirmed to have cobalamin deficiency showed MMA levels greater than 20 micrograms/ml. Data are presented showing the Schilling test results, the comparison of serum cobalamin to urinary MMA levels, and other basic hematologic data. MMA levels are a good indication of cobalamin distribution and function since they are directly related to a cobalamin-dependent metabolic pathway. With rapid, reliable quantitation by mass spectrometry, urinary MMA can now be a useful clinical test.

I remember a young man who attended vegetarian conferences in the 1980s. My son and I got to know him quite well. He had been persuaded to follow a regimen that went way beyond veganism, and believed that this was based on ethical and health considerations. He died very young, and many thought it was due to a host of deficiencies, including b-12. A vegan physician we knew was very concerned about him.
I've known very few vegans who went off the deep end in terms of restricted dietss.

It is true that Hindu vegans living in certain parts of India do not suffer from vitamin B12 deficiency. This has led some to conclude that plant foods do provide this vitamin. This conclusion, however, is erroneous as many small insects, their feces, eggs, larvae and/or residue, are left on the plant foods these people consume, due to non-use of pesticides and inefficient cleaning methods. This is how these people obtain their vitamin B12. This contention is borne out by the fact that when vegan Indian Hindus later migrated to England, they came down with megaloblastic anaemia within a few years. In England, the food supply is cleaner, and insect residues are completely removed from plant foods.

Interestingly, while eggs contain B12, they also contain substances that block absorption,4 a fact that leaves only milk as a good source of B12 for vegetarians. Some studies indicate that B12 is better absorbed from milk than from meat.5 However, one source indicates that B12 in milk is destroyed by boiling.6 Analysis of B12 in pasteurized milk reveals only a 10 percent loss; however pasteurization deforms the milk proteins that aid in B12 absorption
Yet another area for concern is multivitamin products! The late Victor Herbert, a noted B12 researcher, maintains that many multivitamin products contain spurious and even dangerous analogs of B12 possibly formed when crystalline B12 interacts with other nutrients in multivitamin products, such as vitamin C, iron and copper.14
High levels of folic acid can accelerate neuropsychiatric complications in persons with B12 deficiency.15 Since folic acid intakes of vegetarians tend to be high (from green vegetables and from grain products that have been fortified with folic acid), those following a vegetarian lifestyle may be at increased risk of neurological and psychological problems.
Interestingly, the body can recycle over 75 percent of the B12 it uses.16 Used B12 is excreted in bile and then reabsorbed in the small intestine by the same complex process described earlier. Some people have a more efficient recycling system than others and hence can go longer on a vegetarian diet without signs of deficiency. However, more B12 is excreted in the presence of high levels of fiber, a common feature of vegetarian diets.17
Vegan and vegetarian diets present a real danger for growing children because their stores are very low, especially if their mothers avoided animal foods during pregnancy and lactation. The scientific literature contains numerous case studies describing severe anemia, dramatic growth retardation, irritability and delays in the acquisition of motor skills in B12-deficient children from vegetarian families.
In a recent study, researchers assayed cognitive development in 72 young people raised on diets free of all animal products until at least the age of six and then on a diet containing milk and eggs. When compared with children who had eaten normal mixed diets (including meat) all their lives, they scored substantially lower on tests measuring spatial ability, short-term memory and "fluid intelligence," that is, the capacity to solve complex problems, abstract thinking ability and the ability to learn.

Dakle..to je nova zgrada iza 'zelene zgrade', drugi kat
Dodjem tamo, zena narucuje za 20.03.
Prodao sam joj pricu da je doktorica iz laba zvala njih i da su rekli da mogu donjeti urin, i evo ja sam ga donio blabla
Primili su ga i rekli da nazovem za 3 tjedna
Platio sam 12,20kn
Bez uputnice kosta 110,00kn, isto se narucuje i ceka
Eto..
Sada molim sve forumase da naprave isto
Posebno dugogodisnje vegane kao sto su Miu i Vujec
OK??

Super..vuycha je napisao/la:okogi je napisao/la:OK??
Naruciti se mozete preko telefona 01/2367-248
Ali mozda je bolje da napravite kao ja
Kupite sterilnu casicu u prvoj apoteci i odnesite srednji mlaz prvog piskanja u jutro
Velika je sansa da vas prime odmah kao i mene
Pokusajte biti tamo oko 8h u jutro
