FAQs
- What is Transtubular K Gradient calculation? It’s a calculation used to assess the kidneys’ ability to conserve or waste potassium.
- How accurate is the Transtubular K Gradient calculation? The accuracy depends on the method used for calculation and the conditions under which the test is conducted.
- What is the normal range for Transtubular K Gradient? The normal range for Transtubular K Gradient is between 3 and 5.
- What does a high Transtubular K Gradient indicate? A high Transtubular K Gradient indicates hyperkalemia, which is an excessive amount of potassium in the blood.
- What does a low Transtubular K Gradient indicate? A low Transtubular K Gradient indicates hypokalemia, which is a deficiency of potassium in the blood.
- What is the Ion Selective Electrode Method? The Ion Selective Electrode Method is an alternative method for measuring Transtubular K Gradient, known for its high accuracy but slow speed.
- What is Flame Photometry? Flame Photometry is another alternative method for measuring Transtubular K Gradient, known for its quick speed but less accuracy.
