When Should You Order Metabolic Testing in Florence?
When Metabolic Testing May Clarify a Diagnosis
Inborn errors of metabolism testing may be appropriate when symptoms suggest the body is not processing nutrients or producing energy as expected. We recommend considering testing for patients in Florence when a patient has developmental regression, repeated vomiting or lethargy, unexplained seizures, low muscle tone, poor growth, unusual odors, liver concerns, cardiomyopathy, or symptoms that worsen during illness or fasting.
Altered mental status, severe lethargy, persistent vomiting, or signs of metabolic decompensation need immediate emergency evaluation. Testing can help confirm clinical suspicion, but it should never delay stabilization or acute care. For more than 50 years, we have served South Carolina families and providers through clinical genetics, laboratory testing, research, and education. Our statewide clinical services, including a clinical site in Florence, diagnostic laboratory, and clinical and laboratory genetic counselors, are available to help determine the most appropriate next step in caring for your patient.
Red Flags for a Metabolic Evaluation
Metabolic concerns can look different from one patient to the next. Pediatricians, primary care providers, neurologists, and other specialists may consider a clinical evaluation or testing when they see patterns such as:
- Developmental delay, loss of skills, hypotonia, seizures, or movement differences
- Recurrent unexplained illness, vomiting, lethargy, or fasting intolerance
- Unexplained liver dysfunction, cardiomyopathy, or hearing or vision changes
- Family history of early unexplained deaths or known metabolic conditions
A positive or borderline newborn screening result may need additional evaluation. Symptoms may also warrant follow-up even after a typical newborn screen. Newborn screening is an important public health tool, but it does not screen for every inborn error of metabolism.
During fall school routines and viral illnesses, patterns such as poor fasting tolerance, repeated vomiting, or unusual tiredness may become easier to recognize. Guidance from GeneReviews, the American College of Medical Genetics and Genomics, and South Carolina newborn screening resources supports careful documentation. We encourage you to note symptom timing, triggers, diet, medication use, illness history, and relevant family history.
The Correct Test for Your Patient
Metabolic testing often starts with biochemical studies chosen for the patient’s symptoms, history, and clinical presentation. Depending on the presentation, testing may include plasma amino acids, acylcarnitine analysis, urine organic acids, or other targeted studies. Not every patient needs the same testing path.
Biochemical findings may help guide further genetic testing. When clinical findings suggest a genetic cause, we may consider tests such as a single-gene test, a multi-gene panel, or whole exome sequencing. Whole exome sequencing examines many genes at once.
Results need to be interpreted alongside the patient’s medical history and exam findings. A positive result may clarify a diagnosis and guide care planning. A negative result does not rule out every genetic or metabolic condition. A variant of unknown significance, often called a VUS, can also be a result of a genetic test. A VUS is a genetic change, but the significance of that change is unknown. A VUS usually should not be used alone for major medical decisions without more clinical context.
Ordering Metabolic Testing in Florence
To test patients in Florence, start by reviewing our Test Finder. It provides current test availability, specimen requirements, collection instructions, and ordering details. Before collecting a specimen, confirm whether special handling, timing, or shipping steps apply.
A practical ordering workflow includes:
- Complete the appropriate laboratory requisition form
- Request a test kit when one is needed
- Include symptoms, age of onset, newborn screening results, medications, diet, and family history
- Review specimen collection and transport instructions before the sample is obtained.
Clear clinical information helps our laboratory interpret results in context. For questions about current billing codes or laboratory processes, contact our laboratory genetic counselors. Our laboratory genetic counselors are available by phone to discuss test selection, specimen questions, and result interpretation.
When the presentation is complex or the best test is unclear, providers may submit an eConsult when available. Developmental regression, multiple congenital differences, and uncertain results are examples of situations where a genetics consultation may help guide testing.
Preparing Florence Families for Evaluation
Families seen through our Florence clinic need a referral from their healthcare provider. We serve South Carolina residents through statewide clinical services, and telegenetics may be available when appropriate. A genetic evaluation can feel like a lot of information at once, so we help families understand why testing is being considered and what results may mean.
You can encourage families to bring:
- Medical records and previous test results
- A current list of medications and supplements
- Family history details
- Insurance or Medicaid cards
Translation services are available for appointments in any language. During a visit, our clinician or genetic counselor may review the patient’s history, discuss whether testing is appropriate, explain possible results, and discuss next steps.
An evaluation may provide answers or identify areas where additional testing is needed. Families can also learn from our patient stories and support group resources while they wait for more information.
Clarify the Next Steps for Your Patient
For help selecting and ordering genetic testing for patients in Florence, review our Diagnostic Laboratory resources and available testing options. Greenwood Genetic Center can help referring providers determine whether a specific test is appropriate for the patient’s clinical presentation.

FAQs
When Should I Order Metabolic Testing Instead Of Making A Referral?
You may order testing when a specific test is appropriate for the patient’s clinical presentation. A clinical referral or eConsult may be helpful when symptoms are complex, testing choices are unclear, developmental regression is present, or results are uncertain.
Does A Typical Newborn Screen Rule Out An Inborn Error Of Metabolism?
No. Newborn screening identifies specific conditions, but it does not screen for every metabolic condition. Ongoing symptoms can require clinical attention.
Can Families Schedule Directly With The Florence Clinic?
No. We see South Carolina patients by healthcare provider referral. Families concerned about symptoms should speak with their healthcare provider about a referral to Greenwood Genetic Center.
What If Results Are Negative Or Uncertain?
A negative result may not rule out every condition, and a VUS may require further testing or family studies. Results are most useful when reviewed with the patient’s symptoms, history, and other testing.
