Immunoglobulin E (Ig E)
Investigation Result Units Biological Reference Interval

Immunoglobulin E (Ig E) 2.62 IU/mL 0 - 200

• Sample Type : SERUM. • Method : ECLIA. • Note : Normal levels of IgE do not rule out possibility of IgE dependent allergies as the diagnostic sensitivity of the test depends upon elapsed time between exposure to an allergen and testing, patient age and affected target organs. No close correlation has been demonstrated between severity of allergic reaction and IgE levels. • Comments : Immunoglobulin E (IgE) is the most important trigger molecule for allergic information. The level of IgE is low during the first year of life, gradually increases with age and reaches adult levels after 10 years. As IgE is a mediator of allergic response, quantitative measurement can provide useful information for differential diagnosis of atopic and non-atopic disease. Patients with atopic diseases like Allergic asthma, Allergic rhinitis & Atopic dermatitis have moderately elevated IgE levels. Increased Levels : Atopic/Non-atopic allergy, Hyper IgE syndrome, Parasitic infections, IgE Myeloma, Pulmonary Aspergillosis, Immunodeficiency states & Autoimmune diseases. • Uses : 1. Evaluation of children with strong family history of allergies and early clinical signs of disease. 2. Evaluation of children and adults suspected of having allergic respiratory disease to establish the diagnosis and define the allergens. 3. To confirm clinical expression of sensitivity to foods in patients with Anaphylactic sensitivity or with Asthma, Angioedema or Cutaneous disease. 4. To evaluate sensitivity to insect venom allergens particularly as an aid in defining venom specificity in those cases in which skin tests are equivocal. 5. To confirm the presence of IgE antibodies to certain occupational allergens. Disclaimer : 1) The above result relate only to the specimens received and tested in laboratory and should be always correlate with clinical findings and other laboratory markers. 2) Improper specimen collection, handling, storage and transportation may result in false negative/Positive results.

Thyroid Function Test (TFT)
Investigation Result Units Biological Reference Interval

T3 (Triiodothyronine) 1.62 ng/mL 0.93 - 2.31
• Sample Type : Serum.
• Method : ECLIA.
T4 (Thyroxine) 9.93 ug/dl 5.99 - 13.8
• Sample Type : Serum.
• Method : ECLIA.
ULTRA Thyroid Stimulating Hormone (TSH) 2.9 uIU/mL 0.60 - 4.84
• Sample Type : Serum.
• Method : ECLIA.

1) TSH levels are subject to circadian variation, reaching peak levels between 2 - 4.a.m. and at a minimum between 6-10 pm. The variation is of the order of 50% . hence time of the day has influence on the measured serum TSH concentrations. 2) Recommended test for T3 and T4 is unbound fraction or free levels as it is metabolically active. 3) Physiological rise in Total T3 / T4 levels is seen in pregnancy and in patients on steroid therapy. Clinical Use : • Primary Hypothyroidism • Hyperthyroidism • Hypothalamic – Pituitary hypothyroidism • Inappropriate TSH secretion • Nonthyroidal illness • Autoimmune thyroid disease • Pregnancy associated thyroid disorders. • References : - Henry’s Clinical Diagnosis and Management, 23rd edition. -Tietz Fundamentals of Clinical Chemistry and Molecular Diagnosis, 7th edition. •Disclaimer: 1) The above result relate only to the specimens received and tested in laboratory and should be always correlate with clinical findings and other laboratory markers. 2) Improper specimen collection, handling,storage and transportation may result in false negative/Positive results.
