Ingestion of ammonium chloride, hydrochloric acid, or other acidifying salts; The treatment and recovery phases of diabetic ketoacidosis; Volume resuscitation with 0.9% normal saline provides a chloride load, so that infusing more than 3–4L can cause acidosis; Hyperalimentation (i.e., total parenteral nutrition)
Usually the most important unmeasured ion in urine is NH 4 + since it is the most important form of acid excretion by the kidney. [5] Urine NH 4 + is difficult to measure directly, but its excretion is usually accompanied by the anion chloride. A negative urine anion gap can be used as evidence of increased NH 4 + excretion. In a metabolic ...
Hyperchloremia is an electrolyte disturbance in which there is an elevated level of chloride ions in the blood. [1] The normal serum range for chloride is 96 to 106 mEq/L, [2] therefore chloride levels at or above 110 mEq/L usually indicate kidney dysfunction as it is a regulator of chloride concentration. [3]
Urine electrolyte levels can be measured in a medical laboratory for diagnostic purposes. The urine concentrations of sodium , chlorine and potassium may be used to investigate conditions such as abnormal blood electrolyte levels, acute kidney injury , metabolic alkalosis and hypovolemia .
Abnormal kidney function may cause too much or too little urine to be produced. The ability of the kidneys to filter protein is often measured, as urine albumin or urine protein levels, [2] measured either at a single instance or, because of variation throughout the day, as 24-hour urine tests. [citation needed]
Reference ranges for urine tests are described below: Measurement Lower limit Upper limit ... Free catecholamines, dopamine: 90 [3] 420 [3] μg/d Red blood cells (RBCs)
[57] [58] Not all bacteria that cause UTIs produce nitrite, and because it takes time for the chemical reaction to occur, the test is best performed on urine that has been in the bladder overnight. [59] A diet low in vegetables can lead to low nitrate levels in the urine, meaning that nitrites cannot be produced. [50]
[5] [21] A rise in the P CO 2 in the arterial blood plasma above 5.3 kPa (40 mmHg) reflexly causes an increase in the rate and depth of breathing. Normal breathing is resumed when the partial pressure of carbon dioxide has returned to 5.3 kPa. [8] The converse happens if the partial pressure of carbon dioxide falls below the normal range.
