Alkaline phosphatase (AF) is an enzyme found in various tissues in the body, including the liver, bones, kidneys, and the digestive system. It plays a crucial role in the process of breaking down proteins and is involved in bone formation and the transport of fatty acids into and out of cells.
Testing AF levels can be useful for evaluating the health of your liver and bones. It may be recommended if you have symptoms such as fatigue, weakness, weight loss, or jaundice, or if a bone disease is suspected. It can also be part of a routine check-up to monitor your liver function.
AF levels in the blood may indicate the presence of liver diseases, bone diseases, or other conditions. An abnormality from the normal values may suggest liver damage, bile duct obstruction, bone growth or repair, or certain forms of cancer.
A high level of AF may indicate liver damage or diseases, bone diseases such as osteoporosis or Paget's disease, or an obstruction of the bile ducts. It may also be elevated in certain cancers or during the healing of a bone fracture.
A low level of AF is less common but can occur with malnutrition, a deficiency of certain vitamins and minerals, hypothyroidism, or, in rare cases, hereditary conditions affecting the production of the enzyme.
Answers to what people usually want to know.
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit longer. You get an email with a link to your digital result, including a short explanation per value.
