A distribution of parasites amongst hosts is said to be aggregated, or overdispersed, if parasites are found to co-occur in particular hosts more often than if the parasites were distributed at random amongst all hosts. A more precise test would be if the distribution differed significantly from a Poisson distribution; a good heuristic is whether the variance to mean ratio is bigger than unity (in appropriate units). Macroparasites are typically aggregated in their host populations, so that the majority of hosts harbor few or no parasites while a few hosts harbor large parasite burdens. Aggregated distributions are often well described empirically by the negative binomial distribution

More relevant information concerning increased globulin may be obtained by serum protein electrophoresis. Decreased globulin may be seen in congenital or acquired hypogammaglobulinemic states. Serum and urine protein electrophoresis may help to better define the clinical problem

People who have liver disease should only take DRY Vitamin E as your liver has a hard time processing the oil in the liquid form of vitamin E.
Antilymphocyte Serum
Formerly SGPT — Alanine aminotransferase – a protein which, when found in the blood in elevated quantities, generally indicates liver damage. It is found mainly in liver cells and therefore has greater specificity for liver disease, but it offers little other advantage. In most liver diseases, the AST increase is less than that of ALT (AST/ALT ratio is less than 1), except in alcohol-related liver injury where the ratio is usually more than 2. Many exceptions limit the practicality of the ratio. However, a ratio of more than 3 with an inordinate increase in GGT (more than 2 times the alkaline phosphatase) is highly suggestive. Increase of serum alanine aminotransferase is seen in any condition involving necrosis of hepatocytes, myocardial cells, erythrocytes, or skeletal muscle cells

The non-essential amino acids are also essential for health, but can be synthesized in the body from the essential amino acids. Arginine, ornithine, cysteine, cystine, taurine and tyrosine are classified as non-essential amino acids but may be essential for individuals with certain diseases or nutritional concerns. A suboptimal intake of the essential amino acids increases the body’s need for the non-essential amino acids.

It is usually impossible to know if the given result would occur again under similar circumstances, or was a chance event. For this reason, anecdotal evidence should rarely form the basis of treatment recommendations

Anion Gap
Increased serum anion gap reflects the presence of unmeasured anions, as in uremia (sulfate, phosphate), diabetic ketoacidosis (acetoacetate, beta-hydroxybutyrate), shock, exercise-induced physiologic anaerobic glycolysis, fructose and phenformin administration (lactate), and poisoning by methanol (formate), ethylene glycol (oxalate), paraldehyde, and salicylates. Therapy with diuretics, penicillin, and carbenicillin may also elevate the anion gap. Decreased serum anion gap is seen in dilutional states and hyperviscosity syndromes associated with paraproteinemias. Because bromide is not distinguished from chloride in some methodologies, bromide intoxication may appear to produce a decreased anion gap

Although occasionally antibiotics can irritate the stomach, mixing them with foods can impair absorption, thus effectiveness
A protein secreted by cells of our immune system in response to infection. The antibody binds to an ‘enemy’ molecule, in this case, a specific part of the hepatitis C virus. This is meant to prevent the virus from infecting other cells or destroy it. As with other viral infections, the presence of antibodies does not necessarily mean a virus will be eliminated from the body. 2. A protein produced in the blood of vertebrates following exposure to an antigen. The antibody binds specifically to the antigen and thus stimulates its inactivation by other parts of the immune system. The major classes of antibody are immmunoglobulin A, or IgA, found predominantly in bodily secretions like saliva; IgM and IgG which are typically produced sequentially in response to microparasitic infections; and IgE which is often elevated in the response to helminth infections. Only IgG is able to cross the placenta to provide maternal immunity. The Good Guy

The interpretation of this test depends on the first two test results

Antisense Strand
Most genetic material, both RNA and DNA, appears as two strands or chains of nucleotides wrapped together into a double helix – the common picture of DNA. Each nucleotide – A, T, C and G – has an attractive opposite . C attracts G, A attracts T. As a result, one strand, the “sense” strand, contains the information (for example, ATG-AAA) and the other strand, the antisense strand contains the opposite of this information (TAC-TTT – according to pairing rules). Antisense RNA is the “antisense” half of a complete double RNA strand. RNA viruses consist of 2 types – “sense” RNA viruses, whose genetic material consists of the “sense” half of a complete strand, and “antisense” RNA viruses, which have the “antisense” half. Sense RNA viruses can have their genetic material read out directly by the ribosomes of their host cells – antisense RNA viruses must first copy themselves into a “sense” strand of RNA

formerly SGOT — Aspartate aminotransferase – a protein which, when found in the blood in elevated quantities, generally indicates liver damage. (although less specific for liver damage than ALT) present in the kidney ,brain, skeletal muscle, & heart as well as the liver. AST levels also increase in muscle injury, MI, CNS disease, heart failure, and other nonhepatic disorders. Regardless of some nonspecificity, high levels indicate liver cell damage. Values of more than 500 IU/L suggest toxic or acute viral hepatitis.
These high values also occur in heart failure (ischemic hepatitis) and with common duct stones. The high value of the numbers has no prognostic value and does not correlate with the degree of liver damage. AST is reliable and part of routine screening for liver disease. Serial testing provides good monitoring: A fall to normal indicates recovery unless associated with the end stages of massive hepatic necrosis. Increase of aspartate aminotransferase is seen in any condition involving necrosis of hepatocytes, myocardial cells, or skeletal muscle cells. Decreased serum AST is of no known clinical significance
