Potassium (Potassium.K) is a project for stool testing. This is often used in studies of metabolic balance. Patients with severe diarrhea can reach 60mmol / 24h or more. Infants are less able to counterbalance water and electrolytes than adults. It should be noted that potassium can be excreted in large amounts from feces. After secretion of the villus tumor of the colon and rectum, the potassium in the feces can be greatly increased. Potassium is abundant in animal and plant foods. The source of potassium in human body is obtained from food. The potassium intake of healthy people is enough for physiological needs. The absorption of potassium is very complete. Only about 10mmol is excreted from the feces.

Applicable gender: whether men and women apply fasting: not fasting

Tips: Please avoid digging the part of the toilet urine and tap water when collecting, and do not place the feces directly on toilet paper or paper towels. Normal value

The normal value is 5 mmol / 24 h.

Clinical significance

Abnormal results:

Patients with severe diarrhea can reach 60mmol / 24h or more. Infants are less able to counterbalance water and electrolytes than adults. It should be noted that potassium can be excreted in large amounts from feces. After secretion of the villus tumor of the colon and rectum, the potassium in the feces can be greatly increased.

Need to check the crowd:

Patients with severe diarrhea, patients with abnormal K metabolism.

High results may be diseases: infant diarrhea, electrolyte imbalance, chronic diarrhea, gastroenteritis precautions

Requirements for inspection:

1. Please avoid digging the part of the toilet urine and tap water when collecting, and do not place the feces directly on toilet paper or paper towels.

2. To avoid interference with the test results, do not use cotton swabs to dig.

3. Do not collect too much feces to avoid having enough specimens for inspection.

Preparation before inspection:

1. If you need to detect fecal occult blood by chemical method, please avoid eating red meat, liver and spinach, cabbage, broccoli and other foods three days before collection to avoid false positive results.

2. If you use the immunological method to detect fecal occult blood, you do not need to limit the type of diet.

3, because infants and young children are not easy to get a sufficient amount of samples at a time, if you need to collect in separate parts, please temporarily store the samples in the refrigerator to avoid bacterial growth.

Not suitable for people:

This test is a routine check and there are no unsuitable people.

Inspection process

After the stool, use a clean container to take the uncontaminated part of the fecal surface and seal it for inspection.

Not suitable for the crowd

This test is a non-invasive test, so there is no contraindication.

Adverse reactions and risks
