Dear all, Can LLOQ and BLQ terminologies be used interchangeably? Some CROs are using LLOQ while others are using BLQ? What would be the EU and FDA's referred terminologies? Kind regards, Tina. Edit: Category changed. [Helmut] |

Hi Tina, ❝ Can LLOQ and BLQ terminologies be used interchangeably? That’s not a question of terminology, but rather of apples and oranges. LLOQ: (Lower) Limit of Quantification BLQ: Below the (Lower) Limit of Quantification Example: If the LLOQ is 10 ng/mL, any back-calculated value <10 ng/mL should not be reported as a numeric value, but with the character-string “BLQ” instead. In the future maybe the list of commonly used Abbreviations (linked on top of the page) will help. — Dif-tor heh smusma 🖖🏼 Довге життя Україна! ![[image]](https://static.bebac.at/pics/Blue_and_yellow_ribbon_UA.png) Helmut Schütz ![[image]](https://static.bebac.at/img/CC by.png) The quality of responses received is directly proportional to the quality of the question asked. 🚮 Science Quotes |
