Blood Testing
Blood tests for lactate are performed to determine the status of the acid base homeostasis in the body. Blood sampling for this purpose is often by arterial blood sampling (even if it is more difficult than venipuncture), because lactate differs substantially between arterial and venous levels, and the arterial level is more representative for this purpose.
| Lower limit | Upper limit | Unit | |
| Venous | 4.5 | 19.8 | mg/dL |
| 0.5 | 2.2 | mmol/L | |
| Arterial | 4.5 | 14.4 | mg/dL |
| 0.5 | 1.6 | mmol/L |
During childbirth, lactate levels in the fetus can be quantified by fetal scalp blood testing.

Famous quotes containing the words blood and/or testing:
“Slowly the poison the whole blood stream fills.
It is not the effort nor the failure tires.
The waste remains, the waste remains and kills.”
—William Empson (1906–1984)
“Traditional scientific method has always been at the very best 20-20 hindsight. It’s good for seeing where you’ve been. It’s good for testing the truth of what you think you know, but it can’t tell you where you ought to go.”
—Robert M. Pirsig (b. 1928)
