Things to Know About Serum Ferritin Test


The serum ferritin test is a blood test that measures the level of ferritin in the blood. Ferritin is a protein that stores iron in the body, releasing it when required for vital functions. Since iron is vital to produce haemoglobin in the body, which helps carry oxygen through the bloodstream, it is important to maintain the correct level of ferritin for overall health. The serum ferritin test helps doctors to detect various health conditions, such as anemia and iron excess disorders.

Why is the Ferritin Test Done?

The ferritin test plays a vital role in detecting conditions related to iron metabolism. Ferritin is mainly found in the spleen, liver and bone marrow as well as in a small amount in the blood. The test is used to: 

• Diagnosing Chronic Diseases

Ferritin levels can be increased in cases of infection or chronic inflammation. It helps to evaluate the severity of conditions like chronic kidney disease, rheumatoid arthritis, and liver disorders.

• Monitoring Treatment

Those who are receiving treatment for anaemia may need to get ferritin test done on a regular basis. It allows doctors to monitor iron levels and make changes in the treatment accordingly. 

• Checking Iron Level 

The test is done to detect iron overload or iron deficiency. A higher level indicates iron overload, which can lead to conditions like haemochromatosis and a low iron level is a condition where the body cannot make enough iron to produce haemoglobin.

• Assessing Risk for Heart Disease

High ferritin levels have also been related to a higher risk of heart disease. Checking ferritin can help in assessing cardiovascular risk in certain individuals.

When is the Test Recommended?

Healthcare providers typically recommend a serum ferritin test when symptoms suggest abnormal iron levels. These include:

Symptoms of Low Ferritin Levels

• Fatigue

• Pale skin 

• Weaknesses

• Shortness of breath

• Dizziness

• Fast heartbeat

Symptoms of High Ferritin Level 

• Unexplained weight loss

• Fatigue or loss of energy

• Stomach pain

• Joint pain

• Low sex drive

The ferritin test is an effective tool to check iron stores and diagnose health issues related to iron imbalance. People also consider factors like immunity test price and other aspects when choosing comprehensive health screening packages that include ferritin testing.

A Brief Introduction to CBC Test: Meaning, Purpose, and Procedure

Image
A complete blood count (CBC) test is a common blood test to measure and analyse an individual's health. A CBC test is part of a full-body health check-up by trusted medical laboratories. It provides proper information about various blood components, including red blood cells, white blood cells, platelets, haemoglobin, and haematocrit. The doctor prescribes this test for several reasons, such as the detection of conditions, disorders, and infections. Top medical laboratories conduct CBC blood tests at an affordable cost . Why is a CBC Test Required? The CBC test is required to check an individual's overall health and well-being. If one has symptoms like fever, fatigue, bleeding, or weakness, the doctor may order a CBC test. It tells the doctor about the level of red blood cells, white blood cells, platelets, and other blood components. The medical professional analyses the blood components to check for infections or diseases. Along with this, CBC test results can also help d...

What You Should Know About the Thyroid Antibodies Test

Image
A thyroid antibody test is a blood test that measures the amount of thyroid antibodies present in the blood. While normally, the production of antibodies is the body’s way of fighting infection, bacteria, viruses, and other foreign substances, in rare cases, the immune system ends up producing antibodies that attack healthy parts of the body, a condition known as autoimmune disease. When these antibodies attack healthy thyroid cells, they can damage thyroid tissues, impacting the normal functioning of the thyroid gland.  Different Types of Thyroid Antibodies Thyroid peroxidase antibodies (TPOAb): These antibodies can indicate an underactive thyroid (hypothyroidism) caused due to a condition known as Hashimoto’s disease. Thyroglobulin antibodies (TgAb): These antibodies can be a sign of Hashimoto’s disease. Thyrotropin receptor antibodies (TRAb): These antibodies bind to the TSH receptor on thyroid cells, stimulating the gland to produce excess thyroid hormones. They are the primar...

4 Tests to Detect Diabetes Early

Image
  Diabetes is a chronic illness characterised by the body's inability to regulate blood glucose (sugar) levels effectively. This can occur when the body doesn't produce enough insulin or when the cells become resistant to insulin, leading to elevated glucose in the bloodstream. The high levels of blood sugar in the body can lead to numerous health problems that affect the eyes, kidneys, nerves, and heart of a person. One can take tests like random blood sugar, glucose challenge, and HbA1C tests at an affordable price to help determine if a person has diabetes (type 1 or 2) or is on the verge of it. HbA1C Test One of the most common tests to diagnose the blood sugar levels of an individual is the HbA1C test. Also called glycated haemoglobin or haemoglobin A1C test, it measures the glucose levels attached to the haemoglobin. The test evaluates the average blood sugar levels over 3 months through a blood sample. A person with consistent high blood sugar levels might have typ...
