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.

Alkaline Phosphatase (ALP) - description and reference ranges

What is it?

Alkaline Phosphatase (ALP) is an enzyme produced by the liver and bones. It is used as a marker of liver function/damage and high levels of ALP may be an indicator that the liver has been damaged.

It is worth noting that smaller amounts of ALP are found in the placenta of women who are pregnant, and in the intestines.

Reference ranges

If your indicative ALP level is lower than the reference range for our laboratory:

Low levels of ALP are not particularly common. It may imply low levels of zinc in the body or general malnutrition, some types of anemia or thyroid disease

Please discuss this result with your GP.

If your indicative ALP level is higher than the reference range for our laboratory:

Elevated levels of ALP are usually due to a disorder of either the bone or liver.

The liver disorder is usually supported by elevated levels of other biomarkers, such as Bilirubin, Gamma-Glutamyl Transferase (GGT) and Alanine Aminotransferase (ALT).

A bone disorder is usually supported by abnormal measurements for Calcium and Phosphate.

Please 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.
