Pseudohypernatremia and pseudohyponatremia: a linear correction.
BACKGROUND Serum sodium is commonly measured by direct potentiometry (DNa), in blood gas panels, or indirect potentiometry (INa), in metabolic panels run on chemistry analyzers. Abnormal values of the serum non-water fraction interfere with INa, with low values causing pseudohypernatremia (INa > DNa) and high values causing pseudohyponatremia (INa < DNa). Previous attempts to derive a linear co...
متن کاملA pulmonary mass and hyperviscosity.
A 69 year old woman was referred to hospital because of a persistent dry cough and dyspnoea. She has never smoked and was taking captopril for hypertension and thyroxine for hypothyroidism. At age 20 she developed pulmonary tuberculosis which was treated with a left artificial pneumothorax. A few years later during the course of investigation into infertility she was found to have tuberculous e...
متن کاملSpurious sodium results (1) – pseudohyponatremia
This is the first of two linked articles that highlight the spurious sodium values that can occur if an indirect ISE technique is used to analyze plasma samples with abnormal protein or lipid concentration. The focus of this first article is spuriously reduced sodium (pseudohyponatremia) due to increased plasma protein or lipid concentration, whilst the subject of the second [1] is spuriously i...
متن کاملNeonatal hyperviscosity syndrome.
THE HYPERVISCOSITY SYNDROME is a symptom complex associated with decreased blood fluidity, which is generally associated with an increase in erythrocyte mass. The mean cord blood hematocrit is 45±5% and 50 +5% in preterm and term infants respectively if they are born at sea level. Values are somewhat higher in infants born in locations at higher altitudes. A central venous hematocrit of 65% or ...
متن کاملThe hyperviscosity syndrome.
common complication in IgG myeloma. Its occurrence has been ascribed to the presence in the serum of high molecular weight polymers of the IgG proteins. Three patients with IgG myeloma and the clinical hyperviscosity syndrome were investigated, none of whom had IgG polymers in the serum by analytical ultracentrifugation. Relative serum viscosity in these patients ranged from 10 to 17.4 (normal ...
