Serum vitamin B 12 is a medical laboratory test that measure vitamin B 12 only in the blood binding to both transcobalamins. [1] Most of the time, 80–94% of vitamin B 12 in the blood binds to haptocorrin, while only 6–20% is binds to transcobalamin ll. [2] Only transcobalamin ll is "active" and can be used by the body. [1]
For this reason, elevated serum homocysteine over 15 micromol/L and methylmalonic acid (MMA) over 0.271 micromol/L are considered better indicators of B 12 deficiency, rather than relying only on the concentration of B 12 in blood. [2] However, elevated MMA is not conclusive, as it is seen in people with B 12 deficiency, but also in elderly ...
A blood test can be performed to quantify total homocysteine concentration in the plasma, of which approximately 80% is generally protein-bound. Classification of hyperhomocysteinemia is defined with respect to serum concentration as follows: [citation needed] Moderate: 15–30 nmol/mL (or μmol/L) Intermediate: 30–100 nmol/mL; Severe: > 100 ...
High Blood Pressure “High blood pressure can damage blood vessels in the brain, leading to vascular issues that increase dementia risk,” says Smita Patel, D.O., FAASM , a board-certified ...
Several serious, even life-threatening diseases cause elevated serum HC, measured as abnormally high serum vitamin B 12. [2] Transcobalamin II (TC-2), a nonglycoprotein secretory protein of molecular mass 43 kDa, is encoded in the human by the TCN2 gene.
“Vitamin B12 is necessary for normal processing of carbs, proteins, and fats in the body and for the normal formation of red blood cells,” adds Elizabeth Somer, M.S., R.D.N., a dietitian based ...
Diagnosing Vitamin B12 Deficiency and Cancer [38] If cancer is suspected as the cause of vitamin B12 deficiency, several diagnostic steps are necessary: Blood Tests: A simple blood test can measure vitamin B12 levels, along with other markers such as homocysteine and methylmalonic acid, which may also indicate a deficiency.
A nutrient that helps keep our body’s blood and nerve cells healthy and while also helping to make DNA, the genetic material in all of our cells, vitamin B12 also helps prevent megaloblastic ...
