| Criterion | Value | ADA Cut-off |
|---|---|---|
| HbA1c | 6.5% | 5.7–6.4% = prediabetes; ≥6.5% = diabetes |
| Fasting glucose | 122 mg/dL | 100–125 = impaired fasting glucose |
Important note: HbA1c of 6.5% technically meets the ADA threshold for Type 2 Diabetes Mellitus (≥6.5%), but the lab's own reference range (and the ADA 2023 guideline printed in the report) lists 5.7–6.4% as prediabetes and ≥6.5% as "Diagnosing Diabetes." This requires confirmation with a repeat test on a separate day or an OGTT to formally establish the diagnosis of T2DM.
| Test | Purpose |
|---|---|
| Free T4 (FT4) | Distinguish subclinical from overt hypothyroidism |
| Free T3 (FT3) | Assess peripheral conversion |
| Anti-TPO antibody (Anti-Thyroid Peroxidase) | Most sensitive test for Hashimoto's thyroiditis (commonest cause) |
| Anti-thyroglobulin antibody | Supplementary autoimmune marker |
| Thyroid ultrasound | Assess gland size, nodules, heterogeneous echotexture |
| Repeat TSH after 3 months | Confirm persistence (exclude transient elevation) |
| Test | Purpose |
|---|---|
| Repeat HbA1c (fasting, separate day) | ADA requires 2 abnormal tests for T2DM diagnosis |
| Oral Glucose Tolerance Test (OGTT) — 75g | Gold standard for glucose tolerance classification |
| Fasting C-peptide | Assess endogenous insulin secretion |
| Urine microalbumin (spot) | Screen for early diabetic nephropathy |
| Post-prandial glucose (2-hr) | Further characterise glucose homeostasis |
| Test | Purpose |
|---|---|
| Peripheral blood smear | Look for target cells, pencil cells, hypochromia |
| Haemoglobin Electrophoresis / HPLC | Definitive test for thalassaemia trait (elevated HbA2 >3.5% in beta-thal trait) |
| Serum TIBC and transferrin saturation | Distinguish IDA (high TIBC, low saturation) from thalassaemia |
| Reticulocyte count | Assess bone marrow response |
| Serum B12 + MMA (Methylmalonic acid) | Confirm functional B12 deficiency despite borderline serum level |
| Homocysteine | Sensitive marker of B12/folate deficiency |
| Serum Folate | Rule out concurrent deficiency |
| Test | Purpose |
|---|---|
| AST/ALT ratio | >2 suggests alcoholic hepatitis; <1 suggests NAFLD |
| Ultrasound abdomen | Screen for hepatic steatosis, fatty infiltration |
| Fibroscan (Transient elastography) | Assess liver fibrosis stage if NAFLD confirmed |
| Serum ALP | Already normal, but re-check post-treatment |
| Hepatitis B & C serology | Exclude viral hepatitis |
| Test | Purpose |
|---|---|
| Lipoprotein(a) — Lp(a) | Independent CVD risk marker |
| ApoB/ApoA1 ratio | Already done: 0.73 (average risk — reassuring) |
| Fasting repeat lipid panel after 4–6 weeks | Confirm after ensuring strict 12-hr fast |
| Blood pressure measurement | Metabolic syndrome component |
| Waist circumference | Central obesity — metabolic syndrome |
| ECG / stress test | Baseline cardiac evaluation given high TG and possible MetS |
| Test | Purpose |
|---|---|
| PTH (Parathyroid Hormone) | Elevated in secondary hyperparathyroidism due to vitamin D deficiency |
| 24-hr urine calcium | Assess renal calcium handling |
| Ionised calcium | More accurate measure of biologically active calcium |
| Magnesium | Hypomagnesaemia causes hypocalcaemia |
⚠️ Triglycerides of 561 mg/dL place this patient at immediate risk of acute pancreatitis. Urgent lipid-lowering therapy (fibrate + omega-3) and dietary fat restriction should not wait for confirmatory testing.
