Some changes in plasma and urinebiochemistryduring pregnancy are summarized inTable 11.1. Plasmauric acidconcentrations decrease by 25–35% during early pregnancy due to increaseduric acid excretionand clearance. As pregnancy progresses, excretion progressively falls and henceplasma uric acidlevels gradually...
Blood in urine (hematuria) is a common problem that happens to children and adults of all genders. And the good news is that the most common causes of blood in urine – like a urinary tract infection – are easily treatable. Still, it’s generally notnormalto see blood in your urine (...

Elevated δ‐ALA in the blood and urine, as well as elevated protoporphyrin in the blood, support the diagnosis of lead poisoning. Basophilic stippling on a peripheral blood smear also supports this diagnosis, but it is a rare and nonspecific finding. View chapterExplore book Lead toxicity: An...
HUS was defined as hemolytic anemia (hemoglobin < 100 g/L), thrombocytopenia (platelet count < 140 × 109/L) and acute kidney injury (a greater than 50% increase in plasma creatinine from baseline, or urine output less than 0.5 ml/kg/hour for at least six hours). Table ...
is another test that is used to assess kidney function. This test measures how well the kidneys filter out creatinine over a given period. Instead of a blood sample, creatinine clearance is usually determined from a measurement of creatinine in a 24-hour urine sample and from a blood sample ...
However, taking a blood sample in the field for later analysis in the laboratory is not practical or efficient for detaining drivers suspected of driving while impaired (DWI) or driving under the influence (DUI). Urine tests for alcohol proved to be just as impractical in the field as blood...
In 2 puppies, 3 weeks of age, PAH extraction and clear- ance were done without xenon studies. A 23-gauge but- terfly needle was placed into the right renal vein for blood sampling. The right ureter was cannulated by a polyethylene tube, and urine was collected in small graduated ...
Treatment is supportive, with maintenance of good urine output. 2 Delayed hemolytic reaction is due to prior sensitization in a patient who has a nondetectable level of antibody at the time of typing. • These patients present with indirect hyperbilirubinemia and hemoglobinuria several days after ...
