Understanding lab values

Trying to figure out what different lab values mean can be challenging. We hope that these articles will help you understand different types of tests. If you have questions don't hesitate to call. 

What is Bone Age?

If your child has a bone age done, read this to help understand what the numbers mean.

Liver Function Tests: NAFLD

We are finding that liver function is affected by childhood obesity, increasing lifetime risks.

Lead

It is recommended to screen all children for lead poisoning risks at routine intervals. We order testing with the one year labs because children do not show symptoms with low (but at risk) levels.

Tuberculosis (TB) Screening and Testing

Tuberculosis screening is recommended every 6 months for the first two years of life, followed by yearly for the remainder of life. Follow up testing is recommended for those found to be at risk. 

Thyroid Tests

Your thyroid is a bow-tie shaped gland that sits low in your neck. It produces hormones that help your body with metabolism.

Cultures

Cultures can be done from many sources: blood, urine, pus, skin, nail, stool, and throat swab. Cultures are performed to identify a treatable source of fever and other symptoms, or to choose the best treatment for a known infection.

Cholesterol

Cholesterol is found in the body from two sources:  cholesterol we eat, and cholesterol our liver makes.  Dietary cholesterol comes from meat, fish, poultry, and dairy products.  Plants contain no cholesterol. 

Anemia: Low Hemoglobin

We screen all of our patients for anemia (low red blood cell count) at 12 months of age. High risk children (such as those who are symptomatic, have a poor diet, or a history of prematurity) will be screened at additional times.
