This may also be called standard range. In contrast, optimal (health) range or therapeutic target is a reference range or limit that is based on concentrations or levels that are associated with optimal health or minimal risk of related complications and diseases. For most substances presented, the optimal levels are the ones normally found in ...
This shows the levels of albumin and the different immunoglobulins. The serum protein electrophoresis test measures the number of proteins in the serum part of a blood sample. The normal ranges to check for the serum globulin would be about 2.0 to 3.5 grams per deciliter then for the immunoglobulins A, M, and G have different ranges.
Generally, people can be grouped as follows: no immunoglobulin production, immunoglobulin (Ig) M production only, or both normal IgM and IgG production. [23] Additionally, B cell numbers are also highly variable. 12% of people have no detectable B cells, 12% have reduced B cells, and 54% are within the normal range. [22]
IgG1 is present in the bloodstream at a percentage of about 60-70%, IgG2-20-30%, IgG3 about 5-8 %, and IgG4 1-3 %. IgG subclass deficiencies affect only IgG subclasses (usually IgG2 or IgG3), with normal total IgG and IgM immunoglobulins and other components of the immune system being at normal levels.
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
Isolated primary immunoglobulin M deficiency [1] is a poorly defined dysgammaglobulinemia characterized by decreased levels of IgM while levels of other immunoglobulins are normal.
Selective immunoglobulin A deficiency - Selective immunoglobulin A deficiency is classified as an IgA level below 7mg/dl (0.4375 μmol/L) with normal levels of other immunoglobulins. Some people with selective immunoglobulin A deficiency are prone to infections and develop other autoimmune disorders such as lupus, celiac disease and ...
Screening of immunoglobulin levels in relatives of CVID and IgA patients finds a familial inheritance rate of 10% to 20%. In cases where a carrier of such a mutation would like to have children, preimplantation genetic diagnosis (PGD) has been offered. [2] PGD is defined as the testing of pre-implantation stage embryos or oocytes for genetic ...
