Ferritin Blood Test

The iron storage in the body is estimated by the levels of ferritin present in the blood. Serum ferritin is a protein that carries the iron in the blood. The determination of serum ferritin estimates the amount of iron present in the body. Ferritin is found in higher concentrations in spleen, liver and bone marrow where there is a production of blood cells. The amount of ferritin found in the blood is always lesser than these organs. The predominant concentration is often found in the spleen and bone marrow.


Ferritin estimation is an important diagnostic approach in identifying conditions such as anemia, infections and inflammation. The normal reference range of ferritin is 12 - 300 ng/ml in men and 12-150 ng/ml in women. It is recommended that any values below 60 indicate iron deficiency and requires treatment. Low ferritin levels can occur due to heavy menstrual bleeding, inadequate iron in the diet, gastrointestinal bleeding, colon cancer, hemorrhoids or even psoriasis. A person suffering from an underlying condition associated with anemia experiences symptoms such as dizziness, fatigue, headaches, loss of libido, abdominal pain and also joint pains. The ferritin levels are often high in conditions such as hemochromatosis, hemolytic anemia and sideroblastic anemia. Birth control pill and anti thyroid medicines can alter blood ferritin values. Those recovering from surgery or illness are also likely to have lower values of ferritin in the blood.


Although iron supplements are recommended for pregnant women and patients having low iron concentrations, increased levels of iron may often lead to toxicity. Ferritin is stored in the body especially in organs like liver, spleen and bone marrow to enable the balance of iron composition in the body. In iron deficiency anemia, the iron stored is used in the production of blood cells leading to depletion of ferritin levels in the organs.

Bone Marrow Aspiration

Bone marrow refers to the spongy tissue that is found inside the larger bones such as spine, breast bone, hips, ribs, legs and skull. Marrow has two parts – both solid and liquid. If the solid portion of the bone is sampled, it is called biopsy. Aspiration procedure is used to collect the liquid part of the marrow.


Both the procedures show whether the bone marrow is healthy and making normal amounts of blood cells. This procedure is normally used by doctors to diagnose and monitor blood and marrow diseases, including cancer. In bone marrow aspiration, the doctor uses a needle to draw a sample of the fluid portion. For a biopsy, a larger needle is used to take the sample of the solid part.

Most often bone marrow aspiration and bone biopsy is done at once. Together, they make the bone marrow examination. Although they are different procedures, they offer complementary information about bone marrow cells.


Why is it done?

Bone marrow aspiration and biopsy offer detailed information about the condition of the bone marrow and blood cells. In case the blood tests indicate that cell counts are abnormal, and information is not sufficient about a suspected problem, this is done. The doctor may perform bone marrow exam to diagnose a disease condition involving the bone marrow or blood cells:


  • To determine a disease progression
  • To check the iron levels and metabolism and
  • To monitor treatment of a disease.

Pre bone marrow aspiration procedure

It is imperative to inform the doctor about any medications and supplements the patient is consuming. This can increase the risk of bleeding after a bone marrow aspiration. In case of anxiety or worry, better talk to the health care provider so that a sedative medication could be given before the aspiration in addition to a numbing agent through local anesthesia at the site where the needle is inserted.

Bone marrow aspiration is done in a hospital, a clinic or in a doctor's room. A specialist in blood disorders – a hematologist – or an oncologist, who is a specialist in cancer does the procedure with a nurse and a trained technologist. It usually takes about half an hour for the exam and if any intravenous sedation is given, extra time is taken for pre and post procedure care.

The patient's blood pressure and heart rate are checked. Some form of anesthesia is administered before the bone marrow aspiration as it can be painful. For many, local anesthesia is sufficient. You will be fully awake during the aspiration, but the site is numbed to reduce pain. If you are quite anxious, intravenous IV sedation is given before the marrow procedure.


Bone marrow aspiration procedure

The area for inserting the biopsy needle is marked and cleaned. The bone marrow fluid (aspirate) is usually collected from the top ridge of the back of the hipbone, and if it is done from the breast bone or the front of the hip near the groin. In young children and kids, the sample is taken from the lower leg bone, just below the knee. The patient will be made to lie down on the abdomen or side.

The bone marrow aspiration is usually done before the biopsy. A small incision is made to insert the needle easier. A hollow needle is inserted through the bone and into the bone marrow. Several samples are taken and aspiration takes only a few minutes. While the health care team ensures that sufficient quantity of sample is drawn, sometimes a 'dry tap' may occur, that is fluid cannot be withdrawn. The needle is moved for another attempt.


Post aspiration procedure

After the bone marrow exam, pressure is applied to the where the needle was inserted to stop the bleeding. A smaller bandage is placed on the site. If local anesthesia had been administered the patient is asked to lie back for 10-15 minutes and apply pressure on the biopsy site. In case, IV sedation had been given, you are taken into a recovery area as sedatives may cause impaired judgment, memory lapses or slowed response.

Tenderness may be felt for a week or more after the bone marrow exam, and the doctor administers pain reliever. You need to keep the bandage dry for 24 hours and not shower or bathe, or swim or use the hot tub. It is okay to get the aspiration site wet after 24 hours. In case bleeding soaks through the bandage, or does not stop even with direct pressure, consult the doctor. The doctor also needs to be contacted if there is persistent fever, worsening pain, swelling at the procedure site and increasing redness or drainage at the procedure site. Also it is advised to avoid rigorous activity for a couple of days to minimize bleeding and discomfort.


Results from bone marrow aspiration

The sample is sent to a laboratory for analysis. The results are available in a few days. The pathologist or hematologist evaluates the samples to check the health of the marrow and if it has enough healthy blood cells and also for abnormal cells. The doctor confirms or rules out a diagnosis and how advanced the disease is or if the treatment is working. Sometimes, follow-up tests are done.


Risks of bone marrow examination

This is a safe procedure and complications are rare. But some complications include:

Excessive bleeding which can happen in people with low platelet count.
Infection in those with weakened immune systems.
Discomfort that could be long lasting in the biopsy site.
Heart and lung problems can be caused due to penetration of the breastbone.
Sedation can cause allergic reaction, nausea and irregular heartbeats in some.


Uses of bone marrow exams

These are used for many conditions including:


  • Anemia
  • Bone marrow disorders which include myelodysplastic syndrome and myelofibrosis.
  • Blood cell conditions such as Leukopenia, leukocytosis, thrombocytopenia, thrombocytosis, pancytopenia and polycythemia – which produce too few or too many of certain types of blood.
  • Cancers of the bone marrow or of blood including leukemia, lymphomas and multiple myeloma.
  • Cancers that have spread to other areas including breast.
  • Hemochromatosis and
  • Infections.

While problems with bone marrow can create lasting and serious health problems, bone marrow exams, such as aspiration and biopsy are important to help determine the status and extent of problems in the cells to evaluate and determine further treatment and management.



Asthenia

Weakness, loss of strength or lack of energy is described as Asthenia. This weakness results in reduced strength thus making it difficult for a person to perform or complete a task. This condition may be indicative of a larger problem/disease. Asthenia is experienced differently by different people thus making it difficult to understand the underlying problem.


The entire body may be affected or only a part of the body may be affected. Asthenia can affect people belonging to any age group. A person suffering from asthenia may not be in a position to complete any task. Asthenia as a condition may be continuos, chronic or temporary. It is more a symptom than a condition itself. It is not life threatening; but it does affect the quality of life. The weakness experienced can either be perceived or true.


Weakness is classified as true weakness when there is an actual loss in muscle strength and capability that may have been caused due to an injury or muscle defect. Weakness is termed as perceived weakness when the muscles of a person are functioning well and yet he feels unable to complete the task. This type of weakness is non-neuromuscular weakness.


Asthenia symptoms

Symptoms may vary depending on how much of the body is affected; part of the body or the entire body. The symptoms also vary depending on the underlying condition and other symptoms that exist. When the entire body is affected, the symptoms include:


  • Tiredness
  • Flu/Fever
  • Lack of energy
  • Loss of muscle strength
  • Physical discomfort
  • Inability to complete tasks
  • Feeling unsteady/wobbly sensation
  • Slow movements

When only part of the body is affected, the symptoms include slow movement, muscle twitching and muscle cramps. If asthenia is present along with other symptoms like extreme pain, slurred speech, confusion, change in vision etc, it needs immediate medical attention.


Common causes for asthenia include:

Sedentary lifestyle: Leads to muscle waste, muscle fibers are replaced by fat due to inactivity thereby reducing muscle fitness.

Advancing age: With age, the muscles in the body loosen or weaken.

Infection: Infection leads to muscle inflammation thus making it weak.

Chronic diseases: Chronic diseases may reduce blood and nutrient supply to muscles thus making them weak.

Vitamin deficiency; in particular vitamin B9

Anxiety or depression

Adverse effects of certain medicines

Treatment for other diseases like radiation therapy or chemotherapy

Chronic lung disease

Drug abuse.


Asthenia classified as per cause

Asthenia can be classified based on what causes the condition. Common types include:


Infectious asthenia: Any prolonged infection in the body like tuberculosis, hepatitis, infective endocarditis can cause this condition. Asthenia neoplastic: Caused due to cancer.

Asthenia neurological: Parkinson's disease, narcolepsy, multiple sclerosis may cause asthenia.

Asthenia endocrine and metabolic: Hypothyroidism, hyperparathyroidism, misunderstood or unbalanced diabetes, kidney failure and anemia

Asthenia digestive origin: Celiac disease, non-infectious hepatitis, cirrhosis, Hemochromatosis, inflammatory bowel disease

Systemic disease: Auto-immune diseases can affect multiple organs and lead to this condition.

Asthenia cardiovascular: Heart failure, chronic respiratory disorder, arrhythmia, sleep apnea.

Asthenia original toxic or drug: Psychotropic drugs, beta-blockers, calcium channel blockers.

When no cause is identified, asthenia is classified as functional asthenia.


Asthenia treatment

The underlying cause of asthenia determines the treatment. Based on what has caused asthenia, treatment is prescribed.


  • Antibiotics or corticosteroids are prescribed depending on the underlying cause.

  • Correction of hormonal deficiency and vitamin deficiency also helps.

  • Unhealthy lifestyle can lead to functional asthenia. A balanced diet, sufficient sleep and a healthy lifestyle can help overcome the condition.
