A blood test with biochemical analysis is a valuable resource for learning about a child’s health. It gives doctors comprehensive knowledge about the body’s systems and organs, enabling them to identify possible problems early on. Tests of this kind can be used to keep an eye on circumstances, monitor growth, and make sure your child is developing normally.
When a child needs a blood test, parents may worry, but some of that anxiety can be reduced if you know what to expect and how the test can help your child. Regular blood work such as a biochemical test provides important information about your child’s health.
This post will describe why your child may need a biochemical blood test, what the results can tell you, and how to get ready for the procedure. Being knowledgeable can make you feel more assured and ready for your child’s medical needs.
| Test Parameter | What it Shows |
| Hemoglobin (Hb) | Measures oxygen levels in the blood |
| Glucose | Indicates blood sugar levels |
| White Blood Cells (WBC) | Helps check for infections |
| Platelets | Affects blood clotting ability |
| Calcium | Important for bone and muscle health |
| Creatinine | Shows how well the kidneys are working |
| Bilirubin | Helps assess liver function |

Why is it needed?
Blood’s biochemical parameters must be determined in order to evaluate how well the baby’s body is operating. The health of the baby’s vital organs and systems can be assessed based on these parameters, which remain constant for children of the same age and vary with illnesses. See an other article for more information on blood tests in children.
Indications
- Suspect hereditary diseases;
- Assume damage to the child"s internal organs due to various diseases;
- Want to determine the cause of jaundice in a newborn;
- Suspect intrauterine infection;
- Go to clarify the diagnosis;
- Want to check the effectiveness of treatment.
Preparation
The child should refrain from eating or drinking anything other than water for eight to twelve hours prior to the procedure, as the study is conducted on an empty stomach. If you are taking a child for this kind of analysis, make sure he is dressed in a way that will not obstruct the nurse’s access to the cubital vein. Remember to explain to the infant why the arm prick is required and that it will only cause temporary discomfort before proceeding with the manipulation.
Children’s biochemical blood testing is a straightforward but crucial method for evaluating their general health. It aids in the evaluation of the health of vital organs such as the liver and kidneys, the early detection of nutritional deficiencies, and the identification of any underlying medical conditions. Through this test, parents can gain a better understanding of their child’s health and, if necessary, make timely interventions and treatments.
How blood is taken?
A tiny needle is used to extract blood from the heel of a newborn. Blood is drawn from the ulnar vein in children who are older than one month. A tourniquet is used to clamp the area that is marginally higher, increasing the vein’s pressure and causing the vessels to swell more. Following antiseptic agent treatment, the vein is punctured with a needle, and blood is collected into a syringe or specialized test tube. The arm is bent at the elbow and cotton wool is applied to the injection site after the needle is removed.
Where can you take the test?
Children’s clinics and hospitals use procedure rooms for performing the manipulation. You can also get the biochemical blood parameters by getting in touch with private labs.
Normal indicators and decoding
The range of biochemical parameters that can be evaluated in a blood analysis of a child is considerable. Many of them are only examined in relation to specific indications. A biochemical analysis typically contains the following information:
A signpost
Its significance
In infants
In kids aged two months to a year
In kids older than a year
Displays the amount of protein in the child’s blood overall.
Between 12 and 24 months: 56–75 g/l;
Over a 24-month period: 62–82 g/l
They are one of the blood protein fractions that are in charge of both preserving blood pressure and transferring a variety of substances, including bilirubin, fatty acids, hormones, and medications.
They come in four varieties and are likewise a protein fraction. They assist in the immune system’s operation, the movement of hormones and microelements, and the activity of enzymes.
Among the markers of inflammatory activity. It is considered when making a rheumatism diagnosis.
A pigment that develops when heme in hemoglobin breaks down.
A pigment that has joined forces with liver cells’ glucuronic acid. Another name for it is direct.
Another name for this extremely harmful type of bilirubin is indirect bilirubin. It is crucial to identify each of these forms independently when making a differential diagnosis of jaundice.
An enzyme falling under the aminotransferase category. Determining it is crucial for the diagnosis of liver disorders.
An additional aminotransferase enzyme, the level of which is used to gauge the liver’s health.
An enzyme whose measurement aids in the early detection of acute leukemia.
A monosaccharide that is produced when all carbohydrates are broken down by the body. serves as the cells’ energy source.
Between 1.7 and 4.7 mmol/l
Between 3.3 and 6.1 mmol/l
Between 3.3 and 6.1 mmol/l
A substance produced by muscle tissue’s metabolism of proteins. Its level is crucial for determining the kidneys’ health.
Between 35 and 110 mmol/l
Between 35 and 110 mmol/l
Between 35 and 110 mmol/l
A material that emerges when protein molecules break down. When assessing the state of the kidneys, the amount of urea is considered.
Displays the total fat content of the child’s blood.
Fat group’s organic component, crucial for hormone synthesis and cell membranes.
Among the lipid types that are most prevalent in the body.
Proteins that are in charge of lipid transport.
One of the essential components influencing the activation of enzymes, muscle contractions, substance transport across cell membranes, and acid-base balance.
A component that is necessary for many different processes, including blood clotting, muscle contraction, bone health, and cardiovascular system function.
A component necessary for kidney function, the production of gastric juice, and the alkaline balance of blood.
An essential component of teeth and bones, this element is also involved in biochemical reactions within the body.
Children have lower glucose levels, more lactic acid, a different ratio of lipid fractions, and lower cholesterol than adult norms.
Parents who are proactive about their child’s health can benefit from knowing the significance of a biochemical blood test. It can identify possible health problems early on and offers insightful information about a variety of physiological processes.
Working together with a medical expert will help to guarantee that any anomalies are taken care of right away. These tests can be reassuring even though they may initially seem overwhelming because they are a standard component of healthcare.
Keep in mind that your child’s health comes first at all times, and that routine examinations—including blood tests—are essential to their continued well-being.
