Refers to the concentration of chloride ions in the serum. Chlorine is the main anion in human extracellular fluid and plays an important role in regulating the body's acid-base balance, osmotic pressure and water distribution.

Basic Information

Specialist classification: inspection classification: biochemical examination

Applicable gender: whether men and women apply fasting: fasting

Analysis results:

Below normal:
Reduce the loss of fluid in the digestive tract, vomiting, gastrointestinal spasm, acute renal insufficiency, etc.

Normal value:
Serum chlorine (Cl-, Cl): 98-106mmol / L

Above normal:
Increased in acute and chronic glomerulonephritis caused by renal insufficiency, urinary tract obstruction, respiratory alkalosis, excessive chloride intake, hypertonic dehydration.

negative:

Positive:

Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. The alcohol content in the blood directly affects the test results. After 8 pm on the day before the medical examination, fasting should be done to avoid affecting the detection of indicators such as blood glucose in the second sky. Normal value

98 to 106 mmol/L (98 to 106 mEq/L).

Clinical significance

1, increased in acute and chronic glomerulonephritis caused by renal insufficiency, urinary tract obstruction, respiratory alkalosis, excessive chloride intake, hypertonic dehydration.

2, reduce the loss of fluid in the digestive tract, vomiting, gastrointestinal spasm, acute renal insufficiency.

High results may be diseases: pediatric renal tubular acidosis, distal renal tubular acidosis, renal tubular acidosis, type I renal tubular acidosis precautions

First, the precautions before blood draw

1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results.

2. After 8 pm on the day before the physical examination, fasting should be done to avoid affecting the detection of indicators such as blood glucose in the second sky.

3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection.

Second, should pay attention after blood draw

1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma.

2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended.

3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved.

4. If there is localized congestion, use a warm towel after 24 hours to promote absorption.
