Oscillospira

VibrantAmerica (various), Vibrant America

Optimal range:   0 - 20 Relative Abundance

Oscillospira is a common yet rarely cultivated gut bacterial genus. Recently human gut microbiota studies have demonstrated its underlying significance for host health.

Osmolality

Serum

Electrolytes

Optimal range:   275 - 295 mOsm/kg

Osmolality measures the concentration of dissolved particles in a fluid, such as blood, urine, or stool, providing insights into the body’s water balance and kidney function. The osmolality test evaluates the concentration of key substances like sodium, potassium, chloride, glucose, and urea. By assessing these levels, the test helps detect imbalances that may affect hydration, kidney health, and electrolyte status.

In blood osmolality, sodium plays a central role as the main electrolyte, working alongside potassium, chloride, and bicarbonate (CO2) to maintain electrical neutrality and acid-base balance in the body. Sodium intake through diet is typically regulated by the kidneys, which either conserve or excrete sodium to keep blood levels stable.

OSMOLALITY (U)

Urinalysis

Optimal range:   50 - 1200 mOsm/kg

Osmolality (U), also known as urine osmolality, measures the concentration of dissolved particles, such as electrolytes, urea, and glucose, in urine. It provides insight into how well the kidneys are functioning and maintaining the body's fluid balance. By measuring urine osmolality, doctors can evaluate how the kidneys are responding to different conditions, such as dehydration or excessive fluid intake. This test is usually done by analyzing a urine sample, which helps determine the concentration of particles and offers important information about kidney health and the body's ability to regulate water and electrolytes.

Osteocyte

Array 5 Multiple Autoimmune Reactivity Screen, Cyrex Laboratories

Optimal range:   0.7 - 2 ELISA Index

Function:

A star-shaped cell, an osteocyte is an abundant cell found in compact bone. Cytoplasmic extensions, which occupy canals called canaliculi, network osteocytes. Canaliculi are used by osteocytes for the exchange of nutrients and waste through gap junctions. Osteocytes are actively involved in the routine turnover of bony matrix, through various mechanisms. Through a mechanism called osteocytic osteolysis, osteocytes can destroy bone.

Antibodies Appear:

Osteoclastogenesis [4]

Osteopenia [3]

Osteoporosis [3]

Known Cross-Reactions:

Phosphatase I, [1] gliadin [5]

Oxalate

3301 Organix Comprehensive Profile - Urine (mmol/mol creatinine), Genova Diagnostics

Optimal range:   0 - 78 mmol/mol creatinine

Oxalic acid is the metabolic end-product of the glyoxylase pathway and is derived from the oxidation of glyoxylate.

In the cell, the majority of glyoxylate is converted into glycine or glycolic acid. However, in some instances there may be greater oxidation of glyoxylate to oxalic acid. This leads to increased urinary excretion of oxalic acid.

As 80% of kidney stones are calcium-oxalate stones, an increase in oxalic acid is strongly correlated to frequency of urolithiasis.
