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:
“Your kind doesn’t just kill men. You murder their spirits, you strangle their last breath of hope and freedom, so that you, the chosen few, can rule your slaves in ease and luxury. You’re a sadist just like the others, Heiser, with no resource but violence and no feeling but fear, the kind you’re feeling now. You’re drowning, Heiser, drowning in the ocean of blood around this barren little island you call the New Order.”
—Curtis Siodmak (1902–1988)
“Is this testing whether I’m a replicant or a lesbian, Mr. Deckard?”
—David Webb Peoples, U.S. screenwriter, and Ridley Scott. Rachel, Blade Runner, being tested to determine if she is human or machine (1982)
