Pediatric Hematology: What Is It and How Can It Be Diagnosed?

what is pediatric hematology?

Blood diseases are inherently scary for both children and their parents. Helping families manage these conditions effectively while providing compassionate care requires dedication and skill – both attributes on which the pediatricians at St. Hope Pediatrics pride themselves.


Pediatric Hematology


Pediatric hematology is a branch of medicine focused on the study, prevention, diagnosis and treatment of blood diseases in children. These diseases can potentially affect:


  • Red blood cells
  • White blood cells
  • Platelets
  • Blood vessels
  • Bone marrow
  • Lymph nodes
  • The proteins responsible for clotting


Some of the conditions a hematologist can treat include:


  • Leukemia
  • Lymphoma
  • Sickle cell disease
  • Hemophilia
  • Thalassemia
  • Aplastic anemia
  • Clotting disorders
  • Rare genetic blood diseases


How Do Pediatric Hematologists Diagnose Blood Diseases?


Thoroughness and accuracy are extremely important in any type of diagnostic testing, but it’s particularly important when children are involved. Blood diseases can have serious, long-term side effects that can potentially change the rest of a child’s life – or, in a worst-case scenario, cut that young life short.


Early detection of hematological disorders is crucial, as it enables immediate condition treatment and management, improving the long-term outcomes for the child.


The diagnostic process generally entails:


  1. Getting a detailed medical history and performing a physical examination of the child
  2. A frank and honest discussion with parents about symptoms, familial disease history and the child's overall health and lifestyle
  3. A physical examination, during which the doctor will look for physical signs of a blood disorder such as paleness, rashes or enlarged lymph nodes


Blood tests will be performed if the pediatric hematologist suspects the child may have a blood disease. These tests may include a:


  • Complete blood count (CBC) to measure different components of the blood
  • Blood smear to examine the blood cells under a microscope
  • Coagulation tests to assess the blood's ability to clot


There are also more advanced and sometimes invasive diagnostics that may be necessary depending on initial diagnostic results or if the child is exhibiting certain symptoms. These can include:


  • Bone marrow aspiration or biopsy, where a small amount of bone marrow is taken for examination
  • Genetic testing, especially when a hereditary blood disorder is suspected


Diagnosis in pediatric hematology, as with many fields in medicine, has experienced improvements in recent years thanks to technological advancements and breakthroughs in research. Modern diagnostic tools like flow cytometry, cytogenetic analysis and molecular genetic testing now provide even more precise results.


Treating Blood Disorders


After a diagnosis is made, a pediatric hematologist will provide an in-depth explanation of the child’s treatment options. These can vary widely depending on the specific condition. In some cases, simple vigilant observation or medications can be used to manage symptoms. Serious blood disorders may justify more invasive treatments like blood transfusions or even bone marrow transplants.


Some conditions will also require specific lifestyle changes, which can be especially difficult for children. This is one area in which pediatric hematology is unique from adult hematology. It’s not always easy to tell parents or families that they need to do everything in their power to prevent their child from ever suffering even a minor cut or bruise.


Knowing children, parents usually understand that perfect injury avoidance isn’t possible. One of the pediatric hematologist’s most important jobs is to teach parents how to deal with some of the inevitable health emergencies or scares that are going to happen while raising their son or daughter.


While the prospect of dealing with a blood disorder can be overwhelming, parents should remember they are not alone. Their child’s medical team, including doctors, nurses, social workers and other specialists, are there to provide support and guidance through every step of the journey.

Latest News from St. Hope

Changing weather and environmental factors bring new health challenges for children. While many of these issues are common and temporary, they can still be headaches for parents. At St. Hope Pediatrics, we believe prevention and early care are key to navigating seasonal health changes in pediatric care . Colder Weather and Winter When temperatures drop, children tend to spend more time indoors, and that often means more exposure to germs. They’re also in school all winter, spending at least eight hours a day packed in with other kids. Winter ailments can spread like wildfire in those conditions, which is part of why they’re some of the most common. Common Winter Health Challenges ● Colds and flu : Viruses spread more easily in indoor environments with less ventilation, like classrooms. ● Dry skin and eczema flare-ups : Cold air and indoor heating both dry out the skin. ● Asthma aggravation : Cold air can trigger bronchospasms, making asthma worse. ● Seasonal affective disorder (SAD) : Shorter days and less sunlight may impact mood, even in children. Tips for Winter Wellness ● Encourage frequent handwashing and teach them to cover coughs/sneezes. ● Use a humidifier to balance dry indoor air. ● Keep your child’s skin moisturized with fragrance-free lotion. ● Dress them in breathable layers to manage temperature changes. ● Ensure adequate daylight exposure or talk to your doctor about ways to ensure they get adequate vitamin D. Spring Allergies Spring brings beauty, like blooming flowers and budding trees, but also pollen. Seasonal allergies (also known as allergic rhinitis or hay fever) are extremely common in children and can interfere with sleep, school and outdoor play. Common Spring Health Challenges ● Sneezing, runny noses and itchy eyes. ● Coughing and throat irritation. ● Worsening of asthma symptoms. Tips for Childhood Allergy Management ● Keep windows closed during high-pollen days. ● Make sure they shower and change clothes after outdoor play. ● Consider using an air purifier with a HEPA filter if your child has severe allergy symptoms. ● Talk to your pediatrician about safe antihistamines or allergy testing. The Risks of Summer Heat While summer is a favorite season for many kids, the heat can pose serious health risks if not managed carefully. This is especially important since encouraging your child to go outside and be active is key to their growth and development. Parents should take steps to ensure they can get exercise safely. Common Summer Health Challenges ● Heat exhaustion or heatstroke , especially during intense outdoor activities. ● Sunburn caused by UV rays can damage young skin quickly. ● Dehydration is a constant threat as hot weather increases fluid loss through sweat. ● Insect bites from mosquitoes, ticks and other Texas pests are more common during the summer months. Tips for Summer Safety ● Apply broad-spectrum sunscreen (SPF 30+) every two hours. ● Encourage frequent water breaks during outdoor play. ● Dress them in light, breathable clothing and hats. ● Use insect repellent and do tick checks after hikes or park visits. Fall Transition: Back to School, Back to Germs Fall brings cooler temperatures and the start of the school year, both of which can increase your child’s exposure to germs and stress. Common Fall Health Challenges ● Colds, coughs and early flu. ● Stomach bugs spreading at school. ● Stress-related symptoms like headaches and sleep changes. Tips for Fall Readiness ● Reinforce good hygiene habits. ● Make sure your child gets a flu shot early in the season. ● Establish a consistent sleep schedule to support immunity. ● Check in on how they’re doing since the transition back to school can be tough for kids. Keep Your Child Healthy Year-Round With Good Immune Support No matter the season, your child’s immune system benefits from good year-round healthy habits: ● A balanced diet with plenty of fruits, vegetables and whole grains. ● Regular physical activity. ● Adequate sleep of between 9 to 12 hours per day, depending on age. ● Staying current on vaccinations. ● Regular check-ups with your pediatrician. Preventive care is one of the best ways to protect your child from seasonal health issues. A well-child visit is an ideal time to discuss allergies, asthma management, immunity and any concerns you have about upcoming seasonal changes. When to Call the Pediatrician ● Cold or allergy symptoms last more than 10 days or worsen. ● Your child has trouble breathing or wheezing. ● Skin issues become inflamed, painful or infected. ● They show signs of persistent or serious dehydration like dry mouth, no tears or dark urine. ● Fever lasts more than a few days or is very high.
