		Albumin concentrations, when measured as part of a chemistry profile, are determined using a wet chemistry dye-binding technique.
		The accuracy of albumin concentration measured by chemical methods is disputed by the claim that this methodology has no correlation to albumin concentration measured by electrophoresis.
		Pre-albumin is a separate and distinct plasma protein fraction that precedes albumin on electrophoresis, and is involved in the transportation of thyroid hormones.

	Ask an Expert: Prealbumin levels
		Pre-albumin and albumin measure the same thing (visceral protein stores), but are different in that their half life (or the body`s ability to replete the protein are different).
		Albumin has a half life of ~18 days, so it would take almost 3 weeks to notice a change in this lab value.
		Low albumin and pre-albumin levels are an indicator that the body is either using protein for calories (such as in the case of a low calorie diet or starvation), OR the body is losing protein due to a medical condition (such as kidney or other disease).

	Protein electrophoresis - Wikipedia, the free encyclopedia
		In chemistry and medicine, protein electrophoresis is a method of analysing a mixture of proteins by means of gel electrophoresis, mainly in blood serum (blood plasma is not suitable).
		There are two large classes of blood proteins: albumin and globulin.
		They are generally equal in proportion, but albumin is much smaller and lightly negatively charged, leading to an accumulation of albumin on the electrophoretic gel.

	What happens if a pregnant women has raised BP and albumin in urine? - Kidney - DoctorNDTV (Site not responding. Last check: 2007-10-24)
		The exact cause of pre eclampsia is unknown though poor blood flow to the vital organs of the body is responsible for most of the signs including the leakage of albumin/protein in the urine and kidney disease.
		Pre eclampsia can prevent the placenta (which gives air and food to your baby) from getting enough blood.
		Intervention by the doctor is based upon the severity of pre eclampsia, mother and baby’s condition, and the duration/stage of pregnancy.

		The body maintains the serum albumin at the expense of muscular protein: There is decreased synthesis, increased redistribution and decreased catabolism.
		Goldwasser (1997) suggests that albumin may well be an independent indicator of outcome in a variety of clinical settings.

		Albumin is a protein with a relatively long half life of 20 days.
		Low serum albumin has been correlated with an increased incidence of medical complications and disease severity.
		An isolated measurement of serum albumin, however, is not a good indicator since it is influenced by a number of disease processess such as inflammatory disorders, heart disease, liver disease, kidney disease and others.

	Albumin infusion for low serum albumin in preterm newborn infants
		Cartlidge and Rutter (Cartlidge 1986) showed serum albumin levels in the early neonatal period increased significantly with gestational age from a mean of 19 g/litre (90% confidence interval ~12 to ~28 g/litre) below 30 weeks to a mean of 31 g/litre (90% confidence interval ~22 to ~39 g/litre) at term.
		Albumin accounts for approximately 50% of the serum proteins and is the major protein produced by the liver (Vanek 1998).
		Albumin (which comes in a number of commercial preparations with concentrations ranging from 4 - 20%) is also a scarce and expensive resource with hospitals frequently experiencing shortages (Golub 1994).

		A fall in the albumin concentration appears to reflect deterioration, and a rise, recovery.
		This appears to be the primary cause of decreased serum albumin in sepsis.

	Protein Loss in On-Line Hemofiltration - Karger Publishers
		Background: The albumin serum level is one of the most important nutritional indices and is directly correlated to the uremic patient's hemodialysis outcome.
		One of the factors that can interfere with protein metabolism is the possible loss of albumin through the dialysis membrane that can contribute to keeping levels chronically low, especially for high-flux convective treatments requiring high permeability membranes and the removal of high volumes of plasma water.
		Results: The amount of albumin found in the ultrafiltrate was 2.9 ± 1.5 g in post-D and 1.7 ± 0.8 g in pre-D (p < 0.01).

		In multivariate analyses without confounders, only primiparity, low serum albumin levels and absence of diabetes were significantly associated with severe pre-eclampsia.
		Severe pre-eclampsia was associated with low serum albumin (odds ratio [OR], 0.93; 95% confidence interval [CI], 0.90-0.97; P = 0.0001), primiparity (OR, 0.51; 95% CI, 0.33-0.79; P = 0.002) and the absence of diabetes (OR, 0.21; 95% CI, 0.05-0.93; P = 0.04).
		The consistent relationship between low serum albumin levels and adverse maternal and fetal outcomes was independent of proteinuria and implies that hepatic albumin synthesis is altered in severe pre-eclampsia.
