critical low hematocrit and hemoglobin levels

Hemoconcentration does not significantly correlate with important clinical outcome variables of acute pancreatitis including organ failure and mortality rate. Receiver operation characteristics (ROC) curve values for several cut-offs did not result in more ideal levels. The positive predictive value was 24% and the negative predictive value 88%. Sensitivity and specificity of the hematocrit cut-off level of 43.0% for male and 39.6% for female patients to detect necrotizing pancreatitis were 74% and 45%, respectively. Hemoconcentration significantly correlated with the Balthazar score (differential diagnosis between interstitial and necrotizing pancreatitis), stay in ICU, and total hospital stay. However, its specificity, positive predictive value, and total accuracy were lower. Hematocrit, as a single parameter measured on admission, had the same sensitivity and negative predictive value as the more complicated Ranson and Imrie scores obtained only after 48 h. Logistic regression was used to assess the correlation between hemoconcentration and the severity of variables. Hemoconcentration on admission was defined as a hematocrit level >43.0% for male and >39.6% for female patients. In addition to the CT-controlled diagnosis of interstitial/necrotizing pancreatitis, the following variables were used to assess severity: initial organ failure according to the Atlanta classification indication for artificial ventilation and/or dialysis Ranson score adjusted for etiology Imrie score Balthazar score length of stay in intensive care unit (ICU) total hospital stay development of pancreatic pseudocysts indication for operation (necrosectomy) and mortality. They all underwent a CT within 72 h after admission. The role of the hematocrit as an early marker of severe and/or necrotizing pancreatitis has been retrospectively evaluated against the prospectively obtained data. This prospective study covers the years 1988-1999 for 316 patients (202 male, 114 female) with a first attack of acute pancreatitis. Low Hgb levels can be caused by any condition that affects your body’s ability to create red blood cells or conditions that lower red blood cells in your bloodstream.A study was designed to reevaluate hemoconcentration as an early marker of severe and/or necrotizing pancreatitis and compare it against contrast-enhanced CT, the gold standard to diagnose acute necrotizing pancreatitis. You should drink plenty of water, however. You may need to fast - avoiding food or liquids with calories for about 12 hours - if your doctor plans to test the chemistry of your blood at the same time. You don’t need to fast for the Hgb test specifically. You have a medical condition that can affect your Hgb levels.You’ve lost a lot of blood after surgery or a traumatic injury.You don’t have enough iron in your diet.You have parents or other family members who have blood disorders, such as sickle cell anemia.Here are a few other reasons your doctor may order an Hgb test: Abnormal levels of any of these cells can indicate underlying conditions or blood disorders. A CBC test also measures other important components of your blood, such as white blood cells and platelets. The Hgb test may be ordered as part of a complete blood count (CBC) test. If you’re sensitive to getting blood drawn or the sight of blood, have someone come with you and let your provider know. The needle may cause brief discomfort, but the insertion usually lasts less than a minute. The sample is then stored in the tube to be analyzed later at a lab. To take a sample, your healthcare provider extracts blood from a vein by pricking your finger or inserting a needle with an attached tube into the crease of your arm. The Hgb test uses a sample of your blood to determine hemoglobin levels.
