CA 27-29

 $33.49

CA 27-29 is a tumor marker primarily used to monitor breast cancer. It measures a protein released by cancer cells into the blood. Like CA 15-3, it is used to assess treatment response and detect recurrence, but it is not recommended for initial diagnosis due to possible elevation in non-cancerous conditions such as liver disease or benign breast disorders.

Calcium

 $5.99

Calcium, Serum measures the total amount of calcium in the blood, including both bound and free (ionized) calcium. It is essential for evaluating bone health, nerve and muscle function, and heart rhythm. Abnormal levels may indicate conditions such as parathyroid disorders, kidney disease, or certain cancers.

  • Calcium Measures the total calcium in your blood, important for bone health, muscle function, nerve signaling, and blood clotting.

Calcium, Ionized

 $18.49

Calcium, Ionized measures the active, free form of calcium in the blood that is not bound to proteins. It is the physiologically important form of calcium and is crucial for functions like muscle contraction, nerve signaling, and blood clotting. This test is useful when total calcium levels are abnormal or when protein levels (like albumin) may affect total calcium measurements.

  • Calcium, Ionized Measures the active, unbound form of calcium in your blood — considered a more precise reflection of calcium available to your body's cells than total calcium.

Cancer Antigen (CA) 15-3

 $39.49

CA 15-3 (Cancer Antigen 15-3) is a protein that may be elevated in the blood of individuals with certain types of cancer, especially breast cancer. It is primarily used to monitor response to treatment and detect recurrence rather than for initial diagnosis, as levels can also be elevated in non-cancerous conditions.

  • Carbon Dioxide Reflects the bicarbonate level in your blood, a key part of your body's acid-base balance. Abnormal levels can point to metabolic or respiratory issues.

Carbon Dioxide (Serum)

 $5.99

Carbon Dioxide (CO2) in a blood test measures the amount of carbon dioxide in the blood, primarily in the form of bicarbonate. It helps assess the body’s acid-base balance and is commonly included in metabolic panels. Abnormal CO2 levels can indicate issues with lung function, kidney function, or metabolic conditions such as acidosis or alkalosis.
