NOTES FROM THE LAB

Hello! My name is Jamila Quaye and I am a senior biomedical scientist with a specialism in haematology, here at One Day Tests laboratory.

Potassium - description and reference ranges

What is it?

Potassium is a mineral that is one of the key salts or electrolytes in your body. Potassium is important for the conduction of nerve impulses, muscle contraction, maintaining the heart rhythm, and maintaining the fluid balance in the body.

Reference ranges

If your indicative potassium concentration is lower than the reference range for our laboratory:

If you have low potassium levels, you may have a cardio issue, for example an irregular heartbeat. This condition needs to be investigated further.

You can discuss this result with your GP.

If your indicative potassium concentration is higher than the reference range for our laboratory:

If you have high potassium levels, your heart muscle activity may be reduced. This condition needs to be investigated further.

You can discuss this result with your GP.

    CAN A BLOOD TEST SHOW INSULIN LEVELS?

    Many people know that blood tests can measure glucose levels, but fewer realise that insulin itself can also be measured through a blood test. An insulin blood test measures the amount of insulin circulating in your bloodstream and can provide valuable information about how your body is managing blood sugar. This type of testing may help investigate insulin resistance, assess diabetes risk, explore possible causes of low blood sugar, and support the diagnosis of certain metabolic conditions.

    WHAT IS CONSIDERED A HIGH PTAU LEVEL?

    As blood testing for Alzheimer’s disease becomes more widely discussed, many people are asking what a “high” pTau level actually means. In simple terms, a high pTau level means the amount of phosphorylated tau protein detected in the blood is above the laboratory’s normal reference range. Elevated levels are associated with Alzheimer’s related brain changes, particularly abnormal tau tangles and amyloid plaque buildup.
