<\/span>Introduction<\/strong><\/span><\/h2>\n\n\n\n
If\u00a0your\u00a0routine blood test\u00a0shows\u00a0that your alkaline phosphatase (ALP) level is\u00a0below\u00a0the normal range, you\u00a0may wonder\u00a0what it means.\u00a0A low ALP\u00a0result can be\u00a0worrying, but it\u00a0does not always\u00a0mean you have\u00a0a serious health problem.\u00a0The\u00a0result\u00a0needs to be interpreted in context, including your age, symptoms, other blood test results, medicines, diet, and medical history.\u00a0<\/p>\n\n\n\n
This article explains what low ALP can mean, the\u00a0possible causes, symptoms to watch for, how doctors investigate it, and when treatment may be needed.\u00a0<\/p>\n\n\n\n
<\/span>What Is ALP?<\/strong><\/span><\/h2>\n\n\n\nALP\u00a0is an enzyme\u00a0that\u00a0is\u00a0found\u00a0in\u00a0several\u00a0tissues\u00a0of\u00a0the body,\u00a0especially\u00a0the liver, bile ducts, and bones 1<\/a>,2<\/a><\/sup>.\u00a0Doctors often measure ALP\u00a0as part of a liver panel or routine\u00a0blood test. Your report may list it\u00a0as\u00a0ALP,\u00a0ALK PHOS,\u00a0Alk Phos, or alkaline phosphatase.\u00a0<\/p>\n\n\n\n
A\u00a0low\u00a0ALP\u00a0level means the amount of this enzyme in\u00a0your\u00a0blood is below the\u00a0reference\u00a0range\u00a0used by the laboratory. Reference ranges can vary between laboratories and may differ by age, sex,\u00a0and\u00a0pregnancy status.\u00a0A low result should\u00a0not be judged on its own; it is best reviewed alongside your symptoms and\u00a0other test\u00a0results 1<\/a>,2<\/a><\/sup>.\u00a0<\/p>\n\n\n\n

Did You Know?<\/strong>\u00a0<\/p>\n\n\n\n
\n
Most ALP in the blood comes from the\u00a0liver and bones.\u00a0<\/li>\n\n\n\n
In\u00a0some people, especially\u00a0those with blood types O\u00a0or\u00a0B, a fatty meal\u00a0can temporarily raise ALP from the intestine. For this reason, some doctors may ask for a fasting sample.\u00a0<\/li>\n\n\n\n
Children and teenagers often have higher\u00a0ALP levels\u00a0than adults\u00a0because\u00a0their bones are growing.\u00a0<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n
<\/span>What Is the Normal ALP Range?<\/strong><\/span><\/h2>\n\n\n\n
The table below shows one commonly used adult reference range. Your own laboratory may use a different range, so always compare your result with the range printed on your report.\u00a0<\/p>\n\n\n\n

<\/span>Causes of Low ALP<\/strong><\/span><\/h2>\n\n\n
\n
$\"causes$ <\/figure><\/div>\n\n\n
Low\u00a0ALP\u00a0is\u00a0less common than high ALP. It may happen because of nutrition-related\u00a0problems,\u00a0certain\u00a0medical conditions,\u00a0some\u00a0medicines, or, rarely, an inherited bone condition called hypophosphatasia\u00a0(HPP)^{1<\/a>,3<\/a><\/sup>.\u00a0<\/p>\n\n\n\n}
Common\u00a0low\u00a0ALP\u00a0causes\u00a0include:\u00a0<\/p>\n\n\n\n
\n
Low\u00a0zinc\u00a0or\u00a0magnesium:<\/strong>\u00a0These\u00a0minerals\u00a0help many\u00a0body\u00a0processes work normally. Low levels\u00a0of these minerals\u00a0may be linked with low\u00a0ALP1<\/a>,4<\/a>,5<\/a><\/sup>.<\/li>\n\n\n\n
Poor\u00a0nutrition\u00a0or\u00a0low\u00a0protein intake:<\/strong>\u00a0Not getting enough nutrients can lower\u00a0ALP\u00a0in some people1<\/a><\/sup>.<\/li>\n\n\n\n
Vitamin\u00a0B12-related\u00a0anaemia:<\/strong>\u00a0Pernicious anaemia, a condition that affects\u00a0vitamin B12\u00a0absorption, has been associated with\u00a0low ALP1<\/a>,3<\/a>,4<\/a><\/sup>.\u00a0<\/li>\n\n\n\n
Underactive thyroid:<\/strong>\u00a0Hypothyroidism can be\u00a0linked with low ALP levels1<\/a>,3<\/a>,5<\/a><\/sup>.<\/li>\n\n\n\n
Wilson disease:<\/strong>\u00a0This rare condition causes copper\u00a0to build up\u00a0in the body and\u00a0may\u00a0be associated with low ALP, particularly in some liver-related presentations1<\/a>,4<\/a><\/sup>.\u00a0<\/li>\n\n\n\n
HPP:<\/strong>\u00a0This rare inherited\u00a0condition\u00a0affects ALP\u00a0activity\u00a0and can affect bones and teeth.\u00a0In adults, it may cause\u00a0bone pain, dental problems, calcium deposits\u00a0around\u00a0joints, or\u00a0repeated\u00a0fractures1<\/a>,3<\/a>,6<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n
<\/span>Symptoms of Low ALP<\/strong><\/span><\/h2>\n\n\n\nA low\u00a0ALP\u00a0level itself may not cause noticeable symptoms. Symptoms usually occur due to the underlying condition causing low ALP, especially\u00a0HPP 2<\/a>,6<\/a>,8<\/a><\/sup>.<\/p>
