We use the term "renal threshold for hemoglobin" to indicate the smallest amount of hemoglobin which given intravenously will effect the appearance of recognizable hemoglobin in the urine. The initial renal threshold level for dog hemoglobin is established by the methods employed at an average value of 155 mg. hemoglobin per kilo body weight with maximal values of 210 and minimal of 124. Repeat...

BACKGROUND In the setting of an acute coronary syndrome (ACS), anemia has the potential to worsen myocardial ischemia; however, data relating anemia to clinical outcomes in ACS remain limited. METHODS AND RESULTS We examined the association between baseline hemoglobin values and major adverse cardiovascular events through 30 days in 39,922 patients enrolled in clinical trials of ACS. After ad...

INTRODUCTION Hemoglobin A1c (HbA1c) values are influenced by analytical interferences such as HbF and hemoglobin variants and clinical factors such as increased red cell turnover. Although less well-known, demographic factors such as race, age, and sex also influence HbA1c values. The HbA1c reference range should be homogenous in the United States based on the use of National Glycohemoglobin St...

In 1966 and 1971, the authors studied hemoglobin values of about 2,000 women of 10 different occupational groups and different social classes in the same district. The mean values of hemoglobin and serum iron were highest in nursing students followed by urban housewives and nutritionists and lowest in 3 groups of farm wives and shoe factory laborers. The difference in the mean values of hemoglo...

BACKROUND The purpose of our study is to examine the correlation of the residual red bone marrow areas of distal femoral metaphysis with the age, gender, weight and hemoglobin (hgb) values; evaluate the results, and comprehend the importance of these residual areas in the light of the results. MATERIAL/METHODS 140 nonsmoking patients between the ages of 26 and 72 (92 women, 48 men) who had kn...

Abttract: Hemoglobin and the Risk of Cerebral Infarction: The Framingham Study • Risk of cerebral infarction over 16 years was ascertained in 5,185 men and women classified according to their hemoglobin, blood pressure and cigarette habit on entry to the Framingham Study. Within the normal range of hemoglobin values, risk was found to be proportional to the blood hemoglobin concentration in bot...

AIMS/INTRODUCTION To evaluate whether hemoglobin A1c (HbA1c) levels are affected by hemoglobin level and gender. MATERIALS AND METHODS A cross-sectional analysis was carried out in a sample of 87,284 non-diabetic Koreans without anemia who participated in comprehensive health check-ups between January and December 2009 at the Kangbuk Samsung Hospital Total Healthcare Center in Seoul, Korea. W...

Laboratory values for specimens from a case of intravascular hemolysis showed that hemoglobin was significantly increased and thus could interfere with the determination of other analytes. We studied this problem by adding increasing amounts of purified hemoglobin (to a maximum concentration of 19.3 mg/L) to aliquots of pooled serum samples. The hemoglobin significantly interfered with the dete...
