Strep B Test: MedlinePlus Lab Test Information

What happens during a group B strep test?

If you are pregnant, your health care provider may order a swab test or a urine test.

For a swab test, you will lie on your back on an exam table. Your health care provider will use a
small cotton swab to take a sample of cells and fluids from your vagina and rectum.

For a urine test, you will most likely be told to use the “clean catch method” to ensure your sample is sterile. It includes the following steps.

  • Wash your hands.
  • Clean your genital area with a cleansing pad given to you by your provider. To clean, open your labia and wipe from front to back.
  • Start to urinate into the toilet.
  • Move the collection container under your urine stream.
  • Collect at least an ounce or two of urine into the container, which should have markings to indicate the amounts.
  • Finish urinating into the toilet.
  • Return the sample container as instructed by your health care provider.

If your baby needs testing, a provider may do a blood test or a spinal tap.

For a blood test, a health care professional will use a small needle to take a blood sample from your baby’s heel. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. Your baby may feel a little sting when the needle goes in or out.

A spinal tap, also known as a lumbar puncture, is a test that collects and looks at spinal fluid, the clear liquid that surrounds the brain and spinal cord. During the procedure:

  • A nurse or other health care provider will hold your baby in a curled-up position.
  • A health care provider will clean your baby’s back and inject

Strep A Test: MedlinePlus Lab Test Information

What do the results mean?

If you or your child has a positive result on a rapid strep test, it means you have strep throat or another strep A infection. No further testing will be needed.

If the rapid test was negative, but the provider thinks you or your child might have strep throat, he or she may order a throat culture. If you or your child has not already provided a sample, you will get another swab test.

If the throat culture was positive, it means you or your child has strep throat or other strep infection.

If the throat culture was negative, it means your symptoms are not being caused by strep A bacteria. Your provider will probably order more tests to help make a diagnosis.

If you or your child was diagnosed with strep throat, you will need to take antibiotics for 10 to 14 days. After a day or two of taking the medicine, you or your child should start to feel better. Most people are no longer contagious after taking antibiotics for 24 hours. But it’s important to take all the medicine as prescribed. Stopping early can lead to rheumatic fever or other serious complications.

If you have questions about your results or your child’s results, talk to your health care provider.

Reticulocyte Count: MedlinePlus Lab Test Information

What is a reticulocyte count?

Reticulocytes are red blood cells that are still developing. They are also known as immature red blood cells. Reticulocytes are made in the bone marrow and sent into the bloodstream. About two days after they form, they develop into mature red blood cells. These red blood cells move oxygen from your lungs to every cell in your body.

A reticulocyte count (retic count) measures the number of reticulocytes in the blood. If the count is too high or too low, it can mean a serious health problem, including anemia and disorders of the bone marrow, liver, and kidneys.

Other names: retic count, reticulocyte percent, reticulocyte index, reticulocyte production index, RPI
