Yes, liver function tests (LFTs) can come back with low results for some of the enzymes or proteins measured.
Liver function tests (LFTs) can indeed show low results, especially if there is an underlying issue affecting liver function.
What low LFT results might mean?
Low Liver Enzymes:
If the levels of liver enzymes (such as ALT, AST, ALP, or GGT) are below the LFT reference range, it could indicate reduced liver function. However, extremely low levels may be less common and would require further investigation.
Low Total Protein Levels: The liver produces proteins, including albumin and globulins. Low total protein levels may suggest liver dysfunction or malnutrition.
Low Bilirubin Levels: Bilirubin is a waste product processed by the liver. Very low bilirubin levels are uncommon and may not necessarily indicate a problem. However, if it persists, it’s essential to assess the cause.
Certain conditions (e.g., cirrhosis, hepatitis, liver failure) can lead to decreased liver function, resulting in low LFT values.
Medications, malabsorption, or chronic illnesses may also affect liver enzymes and protein levels.
Other Possible Reasons for Low LFTs:
In some healthy individuals, LFT values might naturally fall slightly below the standard reference range. This isn't necessarily a cause for concern, but a doctor can confirm this based on your medical history and other factors.
Deficiencies in protein, vitamins (like B12), or certain minerals can lead to low levels of albumin and other proteins measured in LFTs.
Liver Disease (Less Common): In some advanced liver diseases, liver cells become so damaged that they produce less enzymes, leading to low LFT results. However, this is less common than elevated LFTs in liver disease.
Pregnancy: Mildly low levels of some LFT enzymes are sometimes observed during pregnancy and are usually not a cause for concern.
Underlying Cause: Identifying the underlying cause of low LFTs is crucial for determining the best course of action.
Ruling Out Serious Conditions: While uncommon, low LFTs can sometimes indicate serious liver problems. A doctor can investigate further to rule these out.
what you can do:
Don't hesitate to discuss your low LFT results with a me to understand their significance and get a proper evaluation.
If you're experiencing fatigue, nausea, loss of appetite, or other concerning symptoms, mention them to me during your appointment.
If you have access to the full lab report, look for the reference ranges for each test and compare your results. This might give you a preliminary idea if your values fall below the normal range.
