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.</p> <h3>What Is a Comprehensive Metabolic Panel (CMP)?</h3> <p>The comprehensive metabolic panel (CMP) 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 <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/kidneys-urinary.html/">kidneys</a>&nbsp;and liver are working.</p> <h3>Why Are Comprehensive Metabolic Panels Done?</h3> <p>A CMP is done to learn information about the levels of:</p> <ul class="kh_longline_list"> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/glucose.html/"><strong>Glucose</strong></a>, a type of sugar used by the body for energy. High glucose levels may point to diabetes.</li> <li><strong>Electrolytes:</strong> <ul> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/calcium.html/"><strong>Calcium</strong></a>, which plays an important role in how muscles and nerves work.</li> <li><strong>Sodium, potassium</strong>, <strong>carbon dioxide</strong>, and <strong>chloride</strong>, which help control the body's fluid levels and its acid-base balance. Normal levels of these electrolytes help keep cells in the body working as they should.</li> </ul> </li> <li><strong>Blood urea nitrogen (BUN)</strong> and <strong>creatinine</strong>, which are waste products filtered out of the blood by the kidneys. These levels show how well the kidneys are working.</li> <li><strong>Albumin </strong>and<strong> total protein</strong>, which are needed to build and maintain muscles, bones, blood, and organ tissue. Low levels may be seen with liver or kidney disease, or nutritional problems.</li> <li><strong>Liver tests</strong>: Alkaline phosphatase (ALP), <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/test-alt.html/">alanine aminotransferase (ALT)</a>, <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/test-ast.html/">aspartate aminotransferase (AST)</a>, and <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/test-bilirubin.html/">bilirubin</a>. When these levels are high, it can be a sign of a problem with the liver.</li> </ul> <h3>How Should We Prepare for a CMP?</h3> <p>Your child may be asked to stop eating and drinking for 8 to 12 hours before a CMP. Tell your doctor about any medicines your child takes because some drugs might affect the test results.</p> <p>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.</p> <h3>How Is a CMP Done?</h3> <p>Most blood tests take a small amount of blood from a vein. To do that, a health professional will:</p> <ul> <li>clean the skin</li> <li>put an elastic band (tourniquet) above the area to get the veins to swell with blood</li> <li>insert a needle into a vein (usually in the arm inside of the elbow or on the back of the hand)&nbsp;</li> <li>pull the blood sample into a vial or syringe</li> <li>take off the elastic band and remove the needle from the vein</li> </ul> <p>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.</p> <p>Collecting a sample of blood is only temporarily uncomfortable and can feel like a quick pinprick.</p> <p><img class="left" src="https://kidshealth.org/EN/images/illustrations/bloodTest-400x760-rd1-enIL.gif" alt="drawing blood diagram showing tourniquet and butterfly needle" name="974-031609_BLOODTEST_RD7.GIF" /></p> <p><img class="left" src="https://kidshealth.org/EN/images/illustrations/heelPrick-339x356-rd1-enIL.gif" alt="Diagram showing heel prick. After pricking the infant's heel with the lancet, the technician gently squeezes blood into the vial." name="865-103108_HEELPRICK1-2_RD4.GIF" /></p> <h3>Can I Stay With My Child During a CMP?</h3> <p>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.</p> <h3>How Long Does a CMP Take?</h3> <p>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.</p> <h3>What Happens After a CMP?</h3> <p>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.</p> <h3>When Are CMP Results Ready?</h3> <p>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.</p> <h3>Are There Any Risks From CMPs?</h3> <p>A comprehensive 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.</p> <p>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.</p> <p>If you have questions about the CMP, speak with your doctor or the health professional doing the blood draw.</p>Análisis de sangre: panel metabólico ampliadoEl panel metabólico ampliado es un análisis de sangre que proporciona información a los médicos sobre el equilibrio de líquidos en el cuerpo.
