The prealbumin screen is a blood test that may be used to see if you are getting enough nutrition in your diet. This may be because you have a chronic condition. Or it may be because you have an infection or inflammation, or you suffered a trauma.
Prealbumin is a protein that is made mainly by your liver. Your body uses it to make other proteins. Prealbumin also carries thyroid hormones in the blood.
Reference Range(s):
| ≤5 Days | 6-21 mg/dL | |
| 6 Days-12 Months | Not established | |
| 1-5 Years | 14-30 mg/dL | |
| 6-9 Years | 15-33 mg/dL | |
| 10-13 Years | 20-36 mg/dL | |
| 14-17 Years | 22-45 mg/dL | |
| Adult Males | 21-43 mg/dL | |
| Adult Females | 17-34 mg/dL | |
Prealbumin is decreased in protein-calorie malnutrition, liver disease, and acute inflammation.
