Reticulocyte Count Test

Reticulocyte Count Test

A reticulocyte count is a kind of blood test that basically measures how fast reticulocyte (a kind of RBC without a nucleus) is made by the bone marrow and then released into the blood. Reticulocyte are immature RBCs and they are in the blood for two days before developing into a complete or mature RBC. So in other words, a reticulocyte count helps in measuring the number and percentages of new RBC in the body. It is also known as Retic Count, Reticulocyte Percent, Reticulocyte Index, and Corrected Reticulocyte.

There is no special preparation required for a reticulocyte count. One can easily follow their daily routine prior to the test. No fasting is required unless advised by the doctor. This test is conducted in health care centre, doctor's lab, hospitals, nursing homes etc. The blood sample is obtained by inserting a small needle into the veins of the arm through the skin. It is recommended that the person collecting the sample should wear a half-sleeve shirt so that it becomes easier to collect the sample. Even if one is wearing a full-sleeved shirt, it is often recommended to roll the sleeves.

Reticulocytes are mainly the newly-produced or immature red blood cells without a nucleus. They primarily form and mature in the bone marrow before being discharged into the stream of blood in a human body. The uses of reticulocyte count are as follows - It helps in measuring the new RBC count which, in turn, evaluates the conditions that affect the red blood cells like anemia, bone marrow disorders etc.

It is a report that evaluates the performance of the bone marrow. A reticulocyte count is required when a medical practitioner wants to evaluate the function of the bone marrow. It gives information regarding RBC count, haemoglobin and the functionality of the bone marrow. Depending upon the result further advice is provided by the doctor.

Causes And Symptoms Of Cyclic Vomiting Syndrome in Children!

Cyclic vomiting syndrome (CVS) is characterized by periodic bouts of nausea and vomiting that happens at cyclical intervals. It affects all ages, but is more common in children. The condition is quite stereotypical in that there are paroxysms or bouts of vomiting that is recurrent and follows days of normal health.

Causes: There is no definite reason identified, but it is said to have a strong hereditary correlation. Studies have shown mitochondrial heteroplasmic (abnormal growth of mitochondria, which is a cellular component) to be one of the factors that can lead to CVS. The genetic correlation, however, is very difficult to establish, specifically because vomiting and nausea are common symptoms that occur with most conditions in children. And CVS is most commonly noted with conditions like infections and emotional excitement. Infection could be either tooth decay or sinusitis or anything else. Lack of sleep, anxiety, holidays, allergies, overeating, certain foods, menstruation - a host of factors have been shown to induce CVS. There is also a strong association with migraine and conditions that lead to excessive production of stress hormones.

Symptoms: The syndrome (a group of symptoms) usually has 4 phases:

  1. Symptom-free interval phase: The child is completely normal in this phase, which happens in between bouts.
  2. Prodromal phase: Prodrome is an indication that a disease or a condition is about to happen. In CVS, this is usually nausea and abdominal pain that can last from a few minutes to a few hours. Treatment in this phase can curb the disease. However, there could be some children in whom this may not manifest and the child may directly start with vomiting.
  3. Vomiting phase: Repeated bouts of paroxysmal vomiting happen associated with nausea, exertion, fatigue, and drowsiness.
  4. Recovery phase: As the nausea and vomiting begin to subside, which may take a couple of days, the child returns back to normal slowly. However, the lethargy and energy levels will take a couple of days to return to normal.

Treatment: Treatment again depends on the severity and the phase at which it is being recognized. If a child has repetitive bouts, then the parent and the doctor would have identified a pattern to it.

  1. If the causative agent has been identified, for instance, infection or migraine, then managing that takes care of the CVS also.
  2. If identified during the prodromal phase, again it can be managed with suitable anti-emetic medications.
  3. If identified after full onset, rest and sleep and medications to control nausea and vomiting are required. Adequate hydration with electrolyte replenishment and sedatives can provide additional support.

However, in most cases of childhood CSV, the pattern will be identified and that helps in better management, both the child/parent and the podiatrist. If you wish to discuss about any specific problem, you can consult a Pediatrician.

Anemia (Low Haemoglobin)

If you have anemia, your blood does not carry enough oxygen to the rest of your body. The most common cause of anemia is not having enough iron. Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body.

Anemia has three main causes: blood loss, lack of red blood cell production, and high rates of red blood cell destruction.

Conditions that may lead to anemia include

Anemia can make you feel tired, cold, dizzy, and irritable. You may be short of breath or have a headache.

Your doctor will diagnose anemia with a physical exam and blood tests. Treatment depends on the kind of anemia you have.
