OMX - Urine+Plasma

Overview

The OMX™ Organic Metabolomics Test - Urine + Plasma provides an expanded assessment of metabolic activity by analysing metabolites from both urine and plasma. This combined profile includes organic acids, amino acids and related biochemical markers across major pathways such as energy production, amino acid turnover, nutrient utilisation, neurotransmitter metabolism and detoxification-related processes. Plasma amino acids offer a more stable reflection of the circulating amino acid pool, while urine metabolites highlight shorter-term metabolic outputs.

The panel may be clinically useful when exploring patterns linked with fatigue, mood changes, cognitive variation, physical discomfort or resilience. Plasma metabolites can give insight into longer-term amino acid status and precursor availability, whereas urine provides a dynamic view of intermediary metabolites influenced by mitochondrial output, nutrient demand and microbial activity. Reviewing both matrices together supports interpretation of interconnected pathways and helps illustrate broader metabolic patterns.

OMX™ Urine + Plasma offers a structured way to evaluate metabolic signatures in greater depth by combining stable plasma markers with responsive urinary metabolites. The breadth of information included provides a detailed overview of biochemical activity that may relate to energy production, mood, cognitive clarity, physical comfort or overall metabolic balance.

Indications


  • Fatigue or low energy: Persistent tiredness, reduced stamina or feeling easily depleted.
  • Mood changes: Irritability, low mood or emotional fluctuation that may accompany metabolic imbalance.
  • Cognitive difficulties: Reduced mental clarity, poor focus or forgetfulness.
  • Stress-related symptoms: Feeling overwhelmed, tense or less resilient.
  • Generalised aches or sensitivity: Ongoing stiffness, discomfort or physical sensitivity.
  • Changes in endurance: Feeling out of breath more easily or noticing reduced physical tolerance.
  • Appetite or energy fluctuations: Energy dips after meals, cravings or variable appetite.
  • Digestive discomfort: Bloating, irregular bowel movements or unsettled digestion.
  • Skin symptoms: Irritation, breakouts or changes in skin comfort.
  • Sleep disturbances: Difficulty falling asleep, disrupted sleep or waking unrefreshed.
  • Gradual weight changes: Unexpected or unexplained shifts in weight or appetite.

Practical

Specimen

Urine and plasma

Please be aware that plasma amino acids, if fasting sampling, can be indicative of the amino acid pool (steady state) and are not influenced by short term intake or dietary fluctuations. This is useful for cases of mood disorders or erratic diets. Compared to urine samples, they convey a slightly better look at amino acid requirements and they are not influenced by kidney function.
