Total T3

This  assay  is  a  useful  test  for  Hyperthyroidism  in  patients  with  low  TSH and  normal  T4  levels.  It  is  also  used for  the  diagnosis  of  T3  toxicosis.  It  is not  a  reliable  marker  for  Hypothyroidism.  This  test  is  not  recommended  for general  screening  of  the  population without  a  clinical  suspicion  of  hyperthyroidism.

Total T4

Total  T4  levels  offer  a  good  index  of thyroid  function  when  TBG  is  normal and  non-thyroidal  illness  is  not  present. This  assay  is  useful  for  monitoring treatment  with  synthetic  hormones (synthetic  T3  will  cause  low  total  T4).It  also  helps  to  monitor  treatment  of Hyperthyroidism  with Thiouracil  or other  anti-thyroid  drugs.

TPMT Genotyping

Measurement  of  TPMT  activity  is encouraged  prior  to  commencing  the treatment  of  patients  with  Thiopurine drugs  such  as  Azathioprine,  6-Mercaptopurine  and  6-Thioguanine.  Patients with  low  or  absent  activity  are  at  a heightened  risk  of  drug-induced   bone  marrow  toxicity  due  to  accumulation  of  the  unmetabolised  drug.

TREPONEMA PALLIDUM HAEMAGGLUTINATION(TPHA)

Treponema  pallidum  causes  Syphilis which  presents  in  clinical  stages  termed as  Primary,  Secondary  and  Tertiary Syphilis. This test is specific for Treponema  pallidum  and  does  not  test the  other  spirochetes.

Triglycerides

Increased  triglyceride  levels  are indicative  of  metabolic  abnormality  and along  with  elevated  cholesterol  are considered  a  risk  factor  for atherosclerotic  disease.  High  levels  may be  seen  in  Biliary  obstruction,  Diabetes, Nephrotic  syndrome,  Renal  failure, Metabolic  endocrinopathies  and  may  be medication  induced.

Troponin I

Troponin I is a cardiac marker elevated only in patients suffering from acute Myocardial Infarction. Patients with renal disease or acute muscle injury show normal levels.High sensitivity assays can detect elevated levels of Troponin I (above the 99th percentile of an apparently healthy reference population) within 3 hours after the onset of chest pain

Troponin T

Troponin  T  is  a  marker  of  Acute Myocardial  Infarction  rising  2-4  hours after  the  onset  of  Myocardial  necrosis and  can  remain  elevated  up to  14  days. High  levels  are  also  seen  in  Unstable angina.  It  may  also  be  used  in  monitoring  patients  with  non-ischemic  causes of  cardiac  injury

TSH (Thyroid Stimulating Hormone)

TSH  is  an  early  indicator  of  decreased thyroid  reserve.  This  assay  helps  to diagnose  hypothyroidism  and  hyperthyroidism,  monitors T4  replacement  or  T4 suppressive therapy and quantifies TSH levels in the subnormal range.
