What is the normal level of ALT in the blood?
If you need to know which are the ALT reference ranges or you require more information about the role of ALT in the blood, you can visit normal ALT level in the blood
What does a low ALT level in the blood mean?
A low ALT (Alanine aminotransferase) level in the blood, formerly named glutamic pyruvic transaminase (GPT), it is not usually a matter for concern. In general, it is present in case of an unbalanced diet with vitamin deficit or due to urinary tract infection.
- Mild ALT hypotransaminasemia (0 - 7 U/L in adults):
The ALT level in the blood is a bit low. Low ALT values are usually a positive sign and they are not considered out of range.
It may be a matter of concern if TSH parameter is high that may suggest hypothyroidism or in case an urinary tract infection is present. Talk to your doctor in any of these two circumstances.
Which factors can reduce the ALT level in the blood?
To suffer a particulated health situation can reduce your ALT level in the blood:
- Vitamin deficiency
- Pregnancy
- Urinary tract infection
Which diseases can reduce your ALT level in the blood?
The following diseases can explain an ALT level in the blood lower than normal:
What can I do to increase the ALT level in the blood?
To increase your ALT level in the blood you must follow a balanced diet with a good source of vitamins, especially vitamin B6 (pyridoxine).
The following foods are rich in vitamin B6:
- Meats: Poultry (Chicken, turkey)
- Fruits and vegetables: Bananas, potatoes
- Fish: salmon, sardines
- Nuts, Pistachios
