Calcium-to-Phosphorus Ratio
CA / PHOS
Description
"Calcium-to-Phosphorus Ratio" test measures the balance between calcium and phosphorus, two minerals critical for bone strength and metabolic stability. Doctors often order this test to investigate conditions like osteoporosis, kidney disease, or parathyroid disorders. Imbalances can signal vitamin D deficiency, endocrine dysfunction, or impaired bone metabolism. A blood sample is analyzed to calculate the ratio. Results help guide care strategies involving dietary changes, supplements, or further testing to restore mineral balance and support skeletal and metabolic health.

Test Group Description
Mineral Group: By assessing various parameters related to mineral levels and balance, it provides insights into overall mineral status and associated health considerations.
Optimal Range
For All Individuals:
Conventional Unit: 1.8–2.2 R
SI Unit: Not Applicable
Normal Range
For All Individuals:
Conventional Unit: 1.6–2.4 R
SI Unit: Not Applicable
Results That Differ From The Norm (Direct and Indirect Causes)
Increased levels may indicate:
High calcium intake
Hypophosphatemia (low phosphate levels in the blood)
Low phosphorus intake
Primary hyperparathyroidism (overactive parathyroid glands leading to high calcium levels)
Decreased levels may indicate:
Hyperphosphatemia (high phosphate levels in the blood)
Hypoparathyroidism (underactive parathyroid glands)
Rheumatoid arthritis (chronic autoimmune joint inflammation)
Key Reasons For Testing
Assessment of Mineral Balance: Evaluates the balance between calcium and phosphorus, essential for bone health and overall mineral regulation.
Identification of Metabolic Disorders: Detects abnormalities linked to conditions like kidney-related bone disease or hypoparathyroidism, aiding in diagnosis and treatment.
Bone Health Monitoring: Tracks bone turnover and health in conditions such as osteoporosis or rickets.
Screening for Renal Dysfunction: Identifies kidney problems affecting mineral management by assessing changes in the ratio.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
