Spike antibody levels
-
Does anyone have experience interpreting SARS-CoV-2 spike antibody levels?
I have a patient who received one Moderna in 2021, had Covid-19 in early 2022, no current symptoms, spike antibody level reported at 618. The test was performed by Labcorp Phoenix. They call it semiquantitative and report a number but with no interpretation, saying there isn’t data to interpret it.
Is a single number of value, or should one look for change over time?
The patient’s concern is for possible shedding of him to others or others to him.
