Please note that with all our tests, you need to register your sample ID online before sending the sample to us for traceability reasons. 

An electrolyte blood test is used to measure the levels of electrolytes in a person's blood. Electrolytes carry an electric charge and play a vital role in maintaining proper fluid balance, nerve function, muscle contraction, and other important bodily functions.

This test gives you the levels of Calcium and Magnesium in your blood.

This electrolytes home blood collection kit contains everything you need to collect blood and send it to our laboratory for analysis. Inside, you'll find lancets, instructions, lab request form, labels, tube, tube pouch, prepaid UN3373 envelope, tube holder, swabs, alcohol wipes, and plasters. No need to go to the post office; simply drop off your sample in the nearest red letterbox.

The report will be quantitative, containing actual figures and remarks for results that fall outside the normal range. The report will be sent to your email.

The Role of Electrolytes in Blood

1. **Maintaining Fluid Balance:** Electrolytes play a significant role in regulating the balance of fluids inside and outside cells. Sodium and potassium, in particular, help control the movement of water in and out of cells, maintaining proper hydration levels.

2. **Nerve Signalling:** The transmission of nerve signals relies heavily on the movement of ions, which are charged particles produced by electrolytes. Sodium and potassium ions, for instance, contribute to generating and transmitting electrical impulses that allow muscles to contract and nerves to communicate.

3. **Muscle Contraction:** Calcium is a crucial player in muscle contraction. It helps muscles contract and relax in response to nerve signals. Magnesium also plays a role in muscle function and helps prevent excessive muscle contractions.

4. **pH Balance:** Electrolytes help regulate the pH balance of your blood, ensuring that it remains within a narrow range. Maintaining the right pH is vital for various biochemical reactions and enzymatic processes.
