Excessive protein intake may cause life-threatening episodes of metabolic decompensation and remains a lifelong risk unless treatment is closely monitored, including serum and urine MMA levels. Several studies have suggested that the determination of serum or urinary methylmalonic acid could be a more reliable marker of cobalamin deficiency than direct cobalamin determination.

What is Carnitine? Carnitine helps your body use fatty acids. The body makes small amounts of carnitine. However, if minimum requirements are not met, carnitine dependent functions fail to proceed normally. The measurement of elevated amounts of methylmalonic acid in the blood or urine serves as a sensitive and early indicator of vitamin B12 deficiency.

High methylmalonate in urine

The body makes small amounts of carnitine. However, if minimum requirements are not met, carnitine dependent functions fail to proceed normally. High levels of urine MMA may mean that your vitamin B-12 levels are low. How is this test done? This test needs either a random or 24-hour urine sample. For a 24-hour urine sample, you must collect all of your urine for 24 hours.

24-hour urine. ▷. Requires collection of urine in one jug for 24 hours Methylmalonate (MMA) = if elevated, it reflects insufficient Vitamin B12. ▫. Xanthurenate

Diabetes is a condition in which your blood sugar is too high. 2020-05-28 1981-11-01 2018-03-07 2017-11-01 BARNESS LA, YOUNG DG, NOCHO R. Urinary methylmalonate excretion is increased in rats with an insufficiency of vitamin B(12). Excretion of methylmalonate is not affected by folic acid, vitamin E, or selenium, but is markedly decreased by small amounts of vitamin B(12) added This test measures the amount of methylmalonic acid (MMA) in the blood or urine.

An elevated MMA is a very sensitive and specific marker of B12 deficiency. There is evidence that up to 10% of individuals who have normal or low normal B12 values (between 150 and 400 pg/mL) may

See the description of this EC number in ENZYME. Protein is typically something you want to have plenty of, but this is only with regard to your blood.

But when checked under a microscope, it contains a high number of red blood cells. In some cases, the urine is pink, red, or the color of tea, which you can see without a microscope. Ingestion of proteins and acidic fruits (e.g., cranberries) can cause acidic urine, and diets high in citrate can cause alkaline urine.15 – 17 Urinary pH generally reflects the serum pH, except Borger Fagperson Metylmalonat (MMA) 27.02.2019. Definition.

A high level of MMA can mean that you have a low level of B-12. Vitamin B-12 deficiency is the most common cause of MMA production.

Method for Analyzing Isomers Without Chromatographic Separation Methods Mol Biol. 2016;1378:159-73. doi: 10.1007/978-1-4939-3182-8_18. Authors Mark M MMAU - Overview: Methylmalonic Acid, Quantitative, Urine.

Methylmalonic Acid (Urine) Occasionally, specialized MMA testing may be ordered to help diagnose methylmalonic acidemia, a rare inherited metabolic disorder that occurs in about 1 in 50,000 to 100,000 people. Methylmalonic acid is a vital intermediate in the metabolism of fat and protein.

The urine concentration of methylmalonic acid (MMA) is higher than that of plasma and needs to be normalised for urine creatinine concentration and corrected for the effects of renal impairment or dehydration before interpretation. An elevated MMA is a very sensitive and specific marker of B12 deficiency. There is evidence that up to 10% of individuals who have normal or low normal B12 values (between 150 and 400 pg/mL) may Methylmalonic acid (MMA) (conjugate base methylmalonate) is a dicarboxylic acid that is a C-methylated derivative of malonate.. The coenzyme A linked form of methylmalonic acid, methylmalonyl-CoA, is converted into succinyl-CoA by methylmalonyl-CoA mutase, in a reaction that requires vitamin B 12 as a cofactor. If you do not have sufficient riboflavin, compounds such as adipate, suberate, and ethylmalonate may increase in urine.

Do not allow toilet paper, stool, or anything else to be added to the urine sample. Write down the date and time that the last sample is collected. The urine sample may need to be kept cool during the 24-hour collection period.
