Figure 3. Percentage of fetal samples testing positive by qRT-PCR by preservation category.
Percentage of thymus, endometrium, and serum samples positive by qRT-PCR from fetuses of different preservation categories. Values indicate total number of samples tested within each category and sample type. Statistically significant differences in the % positive samples from fetuses of different preservation categories within a tissue type are denoted using different superscript letters (P<0.05).
