Before you start: Confirm these points first

  1. Confirm the original version and date. The instructions will be updated with revisions, and the translation must be consistent with the original version. First find the revision date or version number in the original text, and then check it with the new version you have to avoid translating the old version and then being overturned by the new version.
  2. Confirm whether the original text can be selected. Try using the mouse to select a text in the PDF. If it can be selected, it means it is a digital version; if it cannot be selected, it means it is a scan or picture-type file, and it needs to be processed according to the method in the previous section.
  3. Create a comparison table of drug names and terminology. Generic names, trade names, excipient names and adverse reaction names are prone to inconsistencies. List the target translations of these words before translation, and then use them in all documents according to the table. This step will save a lot of rework time.
  4. Confirm the purpose and reviewer of the translation. Internal referencing, submissions, and patient readings have different accuracy requirements. After the purpose is determined, decide who will review it to prevent the translation from being used without review.

  7. Submit the final draft to a qualified professional for review, and then file, print or submit it for use after passing the review.

Check each item after completion

After getting the translation, it is recommended to check it item by item according to the table below. Terminology and numbers are two things that take time. Machine translation will provide smooth-sounding, practical but inaccurate translations in places where the context is unclear. Therefore, terminology checking and professional review cannot be omitted.

Check itemsHow to seeWhat to do if there is a problem
Consistency of drug names and terminologyUse the comparison table to search for keywords one by one to see if there are multiple translations for the same concept.Replace them uniformly and add newly emerging words to the reference table
Dosage numbers and unitsCompare numbers, units, decimal points, and symbols in the original and translated texts item by itemModifications are based on the original text; no conversion or rewriting of numbers is made
Table structureCheck whether the number of rows and columns, merged cells, and headers match the originalFix it in the editor, or return to the bilingual version for frame-by-frame viewing
Warning messages and bold noticesCheck whether the warning phrase is fully preserved, and whether the position and emphasis consistency with the original textFill in missing paragraphs and restore the original emphasis format
Subscripts, symbols, and imagesCheck whether chemical formulas, unit symbols, and schematics are retainedSupplement and correct the original text; Parts that cannot be retained are indicated in the translation
Correspondence with the original textCan the corresponding original paragraph be found in the bilingual translation version?Missing paragraphs are filled in, and excess content is deleted without leaving any blank spaces

When verifying, you can first look at the structure, then the numbers, and finally the terminology. If many issues are found, it means the terminology list is still incomplete. The comparison table should be completed first, then retranslated or revised, rather than manually altering sentence by sentence.
