Electrolyte Markers


For: , ,

Electrolyte markers and lab test. Electrolytes are minerals that are found in body tissues and blood in the form of dissolved salts. An altered level of magnesium, sodium, potassium,or calcium may produce one or more of the following symptoms: Irregular heartbeat, muscle spasm, numbness, weakness, blood pressure changes, twitching, convulsions.

Electrolytes are one of the building blocks of health. Their concentration can affect every single process in the body. Muscle contraction, heart, exocrine glands (sweating for example), endocrine system, nervous system, they all depend on the electrolyte balance. The most important and electrolytes whose concentration is particularly vulnerable are potassium, magnesium, sodium, and chloride. Each of those has immense significance in heart muscle contraction, so they are a part of routine heart health lab work as well.

The electrolyte balance maintains the water balance in the body as well. Eating too much salt on one day can result in water retention and instant gain of 2-5 pounds of water (which will slowly wash away as the body adapts to the increased level of sodium in the body).

Depending on which of the electrolytes is out of balance symptoms may vary between palpitation, twitching, convulsions, numbness, weakness, muscle spasm, fatigue, etc.

What does this electrolyte markers test reveal about your health?
This test tells a lot about organs responsible for electrolyte balance maintenance (kidneys and intestines) and about organs directly affected by the fluctuations in the electrolytes concentration (muscles, nervous system, heart health).

You should perform this electrolyte marker test if you:
• Use diuretics regularly
• Feel some of the following symptoms and you can’t explain them:
• Weakness
• Numbness
• Twitching
• Muscle spasms
• Irregular heart rhythm
• Are diagnosed with a kidney or a heart disease
• Are a diabetic
• Had severe diarrhea in the last 7 days

Follow the simple lab test order from Labwork365.
