FT3 + FT4

FT3 + FT4:Measure the active (free) thyroid hormones circulating in blood. They directly reflect thyroid gland activity and are used with TSH to diagnose hyperthyroidism, hypothyroidism, and to monitor thyroid hormone therapy. This test is provided by the Immunology department and typically uses a Serum sample.

The FT3 + FT4 is performed to evaluate clinical parameters relevant to immunology. It helps clinicians diagnose conditions, monitor therapy response, or perform screening based on clinical context.

A trained phlebotomist collects a Serum sample which is processed in a certified laboratory using validated analytical methods. The exact technique depends on the assay (e.g., immunoassay, biochemical analyzer, molecular method).

The test requires a Serum sample. For certain panels or molecular tests alternative matrices (urine, swab, or serum) may be used — check the sample_type column or consult the lab.

Fasting not required unless advised. Specific guidance (e.g., 8–12 hour fast) will be noted for tests where fasting materially affects results.

Reference ranges vary by assay method, patient age and sex, and laboratory. The laboratory report will include method-specific reference intervals. Interpreting results requires clinical correlation by a physician.

Abnormal results can indicate an underlying pathology, effect of medications, or pre-analytical factors (sample handling, fasting status). Always discuss abnormal values with your treating physician; the lab does not provide a clinical diagnosis alone.

Pre-analytical factors (improper fasting, hemolysis, incorrect container), concurrent medications, comorbid conditions, and timing of sample collection can influence results. The lab follows quality controls to minimise analytical variation.

Typical reporting time: Same day or as per lab schedule. Emergency or STAT testing may be possible subject to clinical request and laboratory capacity.

Results are delivered as a digital report (PDF) via email/SMS or via the patient portal. Printed reports are available at the collection centre. Reports include numeric values, units, reference ranges and method notes.

Seralis Lab generally offers home collection for many tests. Home collection availability depends on location and test type; schedule via the website or customer care.

The laboratory uses validated methods, participates in external quality assurance/proficiency testing schemes and follows internal QC protocols to ensure analytical accuracy. The report may include method and CV (coefficient of variation) information on request.

Yes — this is offered as a package. It includes the following tests/parameters: FT3 + FT4

The package includes multiple parameters — see the included_tests or parameters column for a full itemised list.

Booking can be completed online via the Seralis Lab website, by phone, or by visiting a collection centre. Home collection requests can usually be scheduled online.

Check the Seralis Lab website or contact the nearest branch for current pricing; prices may vary by location and promotional offers. Bulk packages, corporate rates and health-check offers may reduce the effective price.

Insurance coverage depends on your insurer and plan. Some diagnostic tests may be reimbursable if medically indicated; keep the medical requisition and receipt for claims.

Urgency depends on the magnitude and clinical context. Significant abnormalities should prompt timely consultation (same day to within a few days) with your treating physician or specialist.

Most diagnostic tests have no absolute contraindications, but special precautions apply for certain procedures (e.g., paediatric sampling, anticoagulated patients). Notify the collection staff about anticoagulants, pregnancy, or difficult veins.

Yes. Many medications and supplements can alter laboratory values. Provide a complete medication history to the ordering clinician and laboratory when relevant.

Repeat testing is commonly used to confirm abnormal or unexpected results, to monitor trends, or to verify response to therapy. Your physician will advise the appropriate interval for retesting.

Yes, with age-appropriate reference ranges and collection technique adjustments. The laboratory reports age- and sex-specific reference intervals where applicable.
