| 词条 | Macroglobulin |
| 释义 |
A macroglobulin is a plasma globulin of high molecular weight.[1] Elevated levels of macroglobulins (macroglobulinemia) may cause manifestations of excess blood viscosity (as is the case for IgM antibodies in Waldenström macroglobulinemia) and/or precipitate within blood vessels when temperature drops (as in cryoglobulinaemia). Other macroglobulins include alpha-2 macroglobulin, which is elevated in nephrotic syndrome, diabetes, severe burns, and other conditions, while a deficiency is associated with chronic obstructive pulmonary disease.
