Lab vocab 1

What an antibody titer is, in everyday words

A titer is a way labs describe how far a sample can be diluted and still show a reaction. In antibody testing, it is one way of talking about how strong a signal looks.

The short version

  1. A titer is a dilution-based measurement, not a diagnosis by itself.
  2. Higher numbers usually mean a stronger lab signal.
  3. Only a clinician can interpret what a result means for you.

01Dilution steps

Labs often dilute a sample in steps and note the last step that still reacts. That last step is reported as the titer.

02What it is not

A titer alone does not say whether you need treatment or whether a product worked for you personally.

03Why research uses them

Studies may track titers over time to see how immune responses change after a vaccine or other product.

04Talk with a professional
