English to German Medical Mathematics & Statistics genetics

"A crossing line parallel to the horizontal axis is drawn near the center of the exponential amplification area (quantitative area), where the fluorescence intensity (*log-converted* value) is linear, and the number of amplification cycles is determined from the intersection between that line and the amplification curves."

Hier geht es um eine klinische Studie (WT1-mRNA). log-converted habe ich noch nie gehört. Worum geht es hier?

Vielen Dank für Eure Vorschläge.
