Health Information For Parents
A blood test is when a sample of blood is taken from the body to be tested in a lab. Doctors order blood tests to check things such as the levels of glucose, hemoglobin, or white blood cells. This can help them detect problems like a disease or medical condition. Sometimes, blood tests can help them see how well an organ (such as the liver or kidneys) is working.
The basic metabolic panel (BMP) is a blood test that gives doctors information about the body’s fluid balance, levels of electrolytes like sodium and potassium, and how well the kidneys are working.
A BMP is done to learn information about the levels of:
Your child may be asked to stop eating and drinking for 8 to 12 hours before a BMP. Tell your doctor about any medicines your child takes because some drugs might affect the test results.
Wearing a T-shirt or short-sleeved shirt for the test can make things easier for your child, and you also can bring along a toy or book as a distraction.
Most blood tests take a small amount of blood from a vein. To do that, a health professional will:
In babies, blood draws are sometimes done as a “heel stick collection.” After cleaning the area, the health professional will prick your baby’s heel with a tiny needle (or lancet) to collect a small sample of blood.
Collecting a sample of blood is only temporarily uncomfortable and can feel like a quick pinprick.
Parents usually can stay with their child during a blood test. Encourage your child to relax and stay still because tensing muscles can make it harder to draw blood. Your child might want to look away when the needle is inserted and the blood is collected. Encourage your child to relax by taking slow deep breaths or singing a favorite song.
Most blood tests take just a few minutes. Occasionally, it can be hard to find a vein so the health professional may need to try more than once.
The health professional will remove the elastic band and the needle and cover the area with cotton or a bandage to stop the bleeding. Afterward, there may be some mild bruising, which should go away in a few days.
Blood samples are processed by a machine, and it may take a few hours to a day for the results to be available. If the test results show signs of a problem, the doctor might order other tests to figure out what the problem is and how to treat it.
A basic metabolic panel is a safe procedure with minimal risks. Some kids might feel faint or lightheaded from the test. A few kids and teens have a strong fear of needles. If your child is anxious, talk with the doctor before the test about ways to make the procedure easier.
A small bruise or mild soreness around the blood test site is common and can last for a few days. Get medical care for your child if the discomfort gets worse or lasts longer.
If you have questions about the BMP, speak with your doctor or the health professional doing the blood draw.
Hypoglycemia occurs when the level of glucose in the blood is lower than it should be.

A blood test might sound scary, but it usually takes less than a minute. Watch what happens in this video for kids.
When blood glucose levels drop too low, it’s called hypoglycemia. Very low blood sugar levels can cause severe symptoms that require immediate treatment.
These videos show what’s involved in getting a blood test and what it’s like to be the person taking the blood sample.
Milk and other calcium-rich foods help build strong, healthy bones. But most kids and teens don’t get enough calcium. Here’s how to make sure that yours do.
Diabetes means a problem with insulin, an important hormone in the body. Find out how children with diabetes can stay healthy and do the normal stuff kids like to do.
The microalbumin-to-creatinine ratio test is most commonly used to screen for kidney problems in teens with diabetes. It may also be used to monitor kidney function in kids and teens who have a kidney disease.
The kidneys perform several functions that are essential to health, the most important of which are to filter blood and produce urine.
Parents of kids who have a chronic kidney disease often worry about what might happen next, how their child feels, and what treatments are likely to be involved. Find answers here.
The bean-shaped kidneys, each about the size of a child’s fist, are essential to our health. Their most important role is to filter blood and produce urine.
Sometimes kids lose fluids and salts through fever, diarrhea, vomiting, or sweating. Here are some tips on preventing or treating dehydration.
A renal ultrasound makes images of your child’s kidneys, ureters, and bladder. Doctors may order this test if they suspect kidney damage, cysts, tumors, kidney stones, or complications from urinary tract infections.
A basic metabolic panel (BMP) is a group of blood tests that provide doctors with clues about how the body is working. Find out why doctors do this and what’s involved for teens.
Doctors order basic blood chemistry tests to assess a wide range of conditions and the function of organs.
