Back to Top Why the Test Is Performed. This test can help determine if a patient has liver disease or kidney disease, or if the body is not absorbing enough protein. Albumin helps move many small molecules through the blood, including bilirubin, calcium, progesterone, and medications.ecreased blood albumin levels may occur when your body does not get or absorb enough nutrients, such as: 1  After weight-loss surgery. 2  Crohn's disease. 3  Low-protein diets. 4  Sprue. 5  Whipple's disease.
A negative number is a number $x$ such that $x+y=0$ for some positive number $y$. In other words, a negative number is an object whose sum with some positive number equals the additive identity. A similar approach can be used to define other mathematical objects: $ 1 x=0$ is an object such that $a+x=a$. $ 2 x=\frac{1}{a}$ is an object such that $xa=1$.
Negative Integers. Each positive integer on a number line has a negative pair, for example 2 is paired with (-2), 5 with (-5) and 50 with (-50). Pairs represent an equal distance away from the zero on a number line, for example 50 is 50 units to the right of zero while (-50) is 50 units to the left of zero.
