Albumin is a vital protein produced by the liver and circulated in the blood plasma. In healthy individuals, its concentration is around 4.0 g/dL, and doctors often monitor this level to assess liver and kidney function. Microalbumin, on the other hand, is a smaller form of albumin found in urine. Normally, its level stays below 30 mg, but values beyond this may serve as an early indicator of kidney damage.
So, how can you determine whether your albumin and microalbumin levels are within the normal range, and at what point should you seek medical assistance? This blog takes a closer look at albumin and microalbumin, their significance and the steps to consider if their concentrations in the body rise above normal.
What is albumin?
Albumin is a globular protein that performs various functions. They aid in blood pressure regulation, nutrition transportation and fluid balance maintenance in the body. Low albumin levels can cause several health issues, including high blood pressure, oedema (swelling) and nutritional deficiencies.
What is microalbumin?
Healthy bodies secrete a small amount of albumin in the urine, called microalbumin. This is not a functional protein. However, elevated values, i.e., between 30 mg and 300 mg/g, indicate early kidney damage (microalbuminuria).
What are the differences between albumin and microalbumin?
Here are some of the major differences between albumin and microalbumin:
| Feature |
Albumin |
Microalbumin |
| Location |
Blood plasma |
Urine |
| Normal levels |
~4.0 g/dL in blood |
<30 mg/day in urine |
| Function |
Maintains oncotic pressure, transports hormones, vitamins and drugs |
No functions |
| Clinical significance |
Low or high levels can indicate liver or kidney issues, malnutrition or dehydration. |
Elevated levels (30–300 mg/day) suggest microalbuminuria, an early sign of kidney damage. |
| Detection method |
Blood test (serum albumin) |
Urine test (spot urine microalbumin or 24-hour collection) |
| Size |
Standard-sized albumin protein |
Smaller-sized fraction of albumin molecules |
Causes of elevated albumin and microalbumin levels
A high level of albumin in the blood can result from dehydration, severe diarrhea, burns or excessive protein intake. Temporary increases can occur due to physical stress or strenuous exercise.
Increased microalbumin levels in urine can indicate early kidney damage, hypertension or early cardiovascular disease.
Early detection of elevated albumin and microalbumin is crucial for timely diagnosis and treatment.
Role of health insurance in case of high albumin & microalbumin levels
Increased levels of albumin and microalbumin can be a sign of renal diseases or kidney damage. In such cases, it is critical to seek medical assistance for early management of the causes. The cost of a doctor’s consultation, diagnostic tests, medicines and regular monitoring can be cumulatively high. However, individuals with a health insurance policy can get financial assistance for all these expenses.
Since the risk of increased albumin and microalbumin is higher in the elderly, applying for a senior citizen health insurance is imperative. It keeps them secured and ready for unforeseen medical emergencies.
Conclusion
Understanding albumin and microalbumin levels is essential for maintaining kidney health. Recognising elevated levels early and seeking timely medical attention can help prevent serious complications. Regular health check-ups are key to monitoring these proteins.

FAQs
1. What is hypoalbuminemia?
Hypoalbuminemia is a medical condition where the level of albumin in the blood is abnormally low.
2. Can diet help increase the low albumin levels?
Yes, high protein sources, such as meat, fish, poultry, eggs, dairy products, legumes, nuts and seeds can help elevate the abnormally low levels of albumin.
3. What is the microalbuminuria diet?
A diet for microalbuminuria is about moderating protein and sodium intake, avoiding processed foods and including more fiber, fruits and vegetables.
