Individuals with diabetes mellitus may excrete small amounts of protein in the urine which may signal the beginning of reduced glomerular filtration. Stabilizing the blood glucose level at this time may delay progression of diabetic nephropathy. Women in the last month of pregnancy may develop proteinuria as the first sign of impending eclampsia. Eclampsia is the gravest form of toxemia of pregnancy. The presence of protein in this situation must be evaluated by the physician in conjunction with other clinical symptoms.Benign transient proteinuria may be the result of: exposure to cold, strenuous exercise, dehydration, and/or high fever. Benign transient proteinuria may also occur during the acute phase of a severe illness.

Ketone bodies are usually absent in urine. The presence of ketones in the urine probably indicates that the body is using fats rather than carbohydrates for energy. High levels of ketones may be present in the urine of individuals with uncontrolled diabetes because the body's ability to metabolize carbohydrates is defective. Detecting the presence of ketones in the urine is a valuable aid to managing and monitoring individuals with diabetes mellitus. Ketonuria is an indication that the insulin dose needs to be increased. Electrolyte imbalance and dehydration occur when ketones accumulate in the blood. If these conditions are not corrected by adjusting the dose of insulin, the patient may develop ketoacidosis and ultimately diabetic coma. Low levels of ketones may be detected during conditions of physiological stress such as fasting, rapid weight loss, frequent strenuous exercise or prolonged vomiting. The presence of ketones in these situations is due to either inadequate intake of carbohydrates or increased loss of carbohydrates.

Specialists in radioassay use radionuclides to determine the chemical makeup of body fluids such as blood and urine. Specialists in blood gas analysis evaluate lung and breathing function by levels of oxygen, carbon dioxide, pH, and hemoglobin with automated tests. Specialists in histology examine cellular and tissue samples using fixation, dehydration, embedding, microtomy, frozen sectioning, staining, and other similar techniques. Histology specialists licensed as technicians can perform specimen processing, embedding, cutting, staining, and frozen sectioning only under the general supervision of a director, supervisor, or technologist. Specialists in cytology process and interpret samples relating cytopathological disease. Non-gynecological cytology preparations can be screen by a specialist in cytology but final review and interpretation must be done by a physician.

Illustrated in the upper and lower photographs are two-lobed, eye glass ("pince nez") nuclei of neutrophils typical for patients with Pelger-Huet anomaly. In addition to the characteristic two lobes connected by a delicate bridge, the dense, homogeneous nuclear chromatin helps to define Pelger-Huet anomaly. Since the peripheral blood smear did not support the diagnosis of appendicitis in this patient, and since abdominal pain localized to the right lower quadrant never developed, the boy was hydrated with intravenous fluid and observed. After hydration, his constitutional symptoms improved and the abdominal pain subsided. In fact, the lad was back on the ski slopes the next afternoon. People entering high altitude where the humidity may be very low are susceptible to dehydration and may experience symptoms related to mountain sickness. Therefore, close observation and hydration may be the best practice in monitoring patients with stories and findings similar to this one. A further lesson here is that technologists must be alert to the possibility of Pelger-Huet anomaly if a high white blood cell count with a high percentage of band neutrophils with strikingly uniform morphology and without toxic granulation are found. Inappropriate therapy or an invasive procedure as was contemplated here may be avoided by a proper smear assessment and clinical corroboration.
