Lactic Acid Test
A Lactic Acid Test is a blood test that measures the level of lactate (lactic acid) made in the body. Lactic acid is a biomarker in the blood of a variety of health problems. A biomarker is a test that, when normalized, predicts a greater "health span" (less disability) and improved lifespan.
The majorly of lactic acid is produced by muscle tissue, red blood cells, and/or bacteria that can be used as an indirect assessment of the oxygen level in tissue. A biomarker is a test that has the potentially of predicting, when interpreted against other markers, your overall morbidity and mortality (how long you live and risk of developing one or more degenerative diseases). Below are some of the reasons why Dr. Wald requests serial measurements of lactic acid
According to Dr. Wald, "...like other biomarker tests lactic acid levels vary and knowing the extent of these variations (highs and lows) helps to personalize and tailor natural approaches to excessive lactic acid levels. "
It can also be a determining factor towards uncovering the cause and course of lactic acidosis, a serious and sometimes life threatening condition induced by the build up of lactate. However, a large segment of the population suffers from low level lactic acidosis that may contribute to serious health problems. This Low Level Lactic Acidosis is largely under-appreciated and under-diagnosed by traditionally trained physicians. Scientific support for its existence and health and disease implications are well described (see: J of Clinical Endocrinology, University of California, L. Frassetto, Potassium bicarbonate Reduces Urinary Nitrogen Excretion in Postmenopausal Women (82:254-259, 1997).
Through a small sample of blood, a lactic acid test can uncover the cause of high acidity (low pH) of the blood and thus unmask smoldering conditions that are or may potentially affect your health now and in the future.
Serial measurements of lactic acid are necessary for proper interpretation of physiological trends and response to our therapeutic efforts.
WHY WE PERFORM LACTIC ACID TESTS
To check for lactic acidosis and sub-clinical lactic acidosis
To determine the cause of low pH of the blood
To determine the cause of chronic pain
To determine the cause of chronic inflammation
To determine the effectiveness of exercise
To determine the effectiveness of dietary interventions
To determine the effectiveness of stress-reduction strategies
To determine the degree of hypoxia (lack of oxygen) in tissue
To determine the physiological state and the degree of perfusion of body tissue
