Check Your Symptoms

Signs Your Fatigue is Caused by a Medical Deficiency

If you experience any of the following indications, this screening panel provides targeted clinical clarity.

Unrefreshing Sleep & Morning Exhaustion

Waking up feeling completely drained even after sleeping 7 to 9 hours.

Brain Fog & Poor Concentration

Struggling with focus, mental clarity, memory recall, and afternoon cognitive crashes.

Physical Weakness & Breathlessness

Feeling out of breath climbing stairs, muscle weakness, or rapid heartbeats with light activity.

Cold Hands, Pale Skin & Brittle Nails

Classic symptoms of occult iron deficiency or an underactive thyroid gland (hypothyroidism).

Diagnostic Parameters

What Key Biomarkers Are Tested & Why

Our pathology panels test specific laboratory markers to detect subtle subclinical deficiencies before they manifest into severe conditions.

Serum Ferritin & Iron Profile

Iron Studies

Measures stored cellular iron reserves. Low ferritin is the #1 unrecognized cause of persistent female fatigue.

Full Blood Count (Hemoglobin, RBC, Hematocrit)

Hematology

Detects microcytic (iron deficiency) or macrocytic (B12/folate) anemia affecting oxygen delivery to organs.

Thyroid Stimulating Hormone (TSH) & Free T4

Endocrinology

Evaluates thyroid gland activity. An underactive thyroid significantly slows down metabolic energy output.

25-Hydroxy Vitamin D & Vitamin B12

Vitamins

Crucial for cellular ATP production, mitochondrial energy synthesis, and neurological health.

Fasting Blood Glucose & HbA1c

Metabolic

Screens for insulin resistance and glucose crashes that cause extreme afternoon lethargy.

Liver & Renal Function Profile

Organ Function

Ensures proper metabolic detoxification and electrolyte equilibrium.
