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

With high levels of uric acid in your blood, as a result of your disease, the uric acid will collect and form crystals in your kidneys. This may occur during chemotherapy, and may cause your kidneys to fail. Hydration and urinary alkalinization are used with high doses of methotrexate (MTX) to prevent precipitation of the drug in the renal tubules and consequential nephrotoxicity. The quantitative effect of these measures on the renal clearance of MTX was studied in 8 patients with normal renal function, and in 3 patients with reduced renal function.
Without urination, toxins build up, causing problems with the bladder an Creatinine is a waste product normally excreted by the kidneys, which is passed in urine. While creatinine itself is caused by muscle metabolism, its presence in urine indicates how well the kidneys are functioning.

The measurement of elevated amounts of methylmalonic acid in the blood or urine serves as a sensitive and early indicator of vitamin B12 deficiency. Elevated levels of methylmalonic acid can also result from inherited defects of enzymes involved in methylmalonic acid metabolism called methylmalonic acidemia (methylmalonic aciduria).
Methylmalonic aciduria is a genetically heterogeneous disorder of methylmalonate and cobalamin (cbl; vitamin B12) metabolism. Isolated methylmalonic aciduria is found in patients with mutations in the MUT gene causing partial, mut(-), or complete, mut(0), enzyme deficiency. This form is … Methylmalonic Acid Urine Test will be between $99.00 and $399.00.
Urine albumin measurement and reporting is critical to the early detection and treatment of chronic kidney disease. Read about urine albumin standardization. Along with estimated GFR, urine albumin measurement and reporting is critical to t
More than 29 million Americans have diabetes, but more than a quarter of them don’t Methylmalonic acid is elevated in vitamin B12 deficiency. Serum and urine concentrations of MMA are elevated in cobalamin deficiency, due to a decreased The measurement of elevated amounts of methylmalonic acid in the blood or urine serves as a sensitive and early indicator of vitamin B12 deficiency.

This test is used to diagnose a mild and early shortage of vitamin B-12. 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. Why do I need this test? You may have this test if your healthcare provider suspects that you have a vitamin B-12 deficiency. Causes of high MMA include: B12 deficiency, most often due to a B12-poor diet, issues with nutrient absorption, or drugs that deplete B12 levels (e.

The odd numbered fatty acids containing 15, 17, 19, or 21 carbon atoms (heptadecanoic acid, nonadecanoic acid, tricosanoic acid, pentadecanoic acid) accumulate in vitamin B12 deficiency.
Empty your bladder completely first thing in the morning without collecting your urine Note the time. 2018-06-05 · High levels of methylmalonic acid in the blood may also be an indication of kidney disease. Kidney disease is often identified through the use of other blood and diagnostic tests.

2019-11-22 · The urine MMA level (reference interval: 0-3.6 mmol/mol creatinine) is helpful not only in monitoring patients with methylmalonic aciduria but also in evaluating vitamin B-12 status. [ 5 ] There are many factors that come into play with the results of a methylmalonic blood test.

To achieve an accurate determination of MMA without GC separation, we had to overcome the interference from succinic acid, an isomer physiologically present in plasma (0–32 μmol/L) and urine (adult reference interval, 0.5–16 mmol/mol creatinine) at concentrations higher than MMA (plasma, 0–0.4 μmol/L; urine, 0–3.6 mmol/mol creatinine). High level of methylmalonic acid in the urine is commonly linked to vitamin B12 deficiency. This is because vitamin B12 is needed for the breakdown of methylmalonic acid. When this nutrient is not available in sufficient amounts, the acid is not broken down and starts to accumulate in the body. 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. The urine sample must include the last urine that you pass 24 hours after starting the collection.
