TABLE 1.

Detection rates of CAP/CTM among DBS or DPS prepared from plasma samples within each of five sampling strata

Stratum and plasma VL	No. of plasma samples	No. of DBS prepared from plasma samples	No. of DBS in which VL was detecteda	DBS detection rate (CI)b	No. of DPS prepared from plasma samples	No. of DPS in which VL was detectedc	DPS detection rate (CI)
undetectable	117	113	18	15.9 (9.1–22.7)	17	2	11.8 (0.00 to 27.5)
<LODd	218	215	209	97.2 (95.0–99.4)	163	18	11.04 (0.00 to 15.9)
LOD to 999 copies/ml	309	303	301	99.3 (98.4–100)	222	66	29.73 (23.7–35.8)
1,000–9,999 copies/ml	65	64	64	100	50	48	96.0 (90.5–1.0)
≥10,000 copies/ml	129	128	128	100	94	93	98.9 (96.9–1.0)
Total	838	823	720		546	227

^aIncludes any DBS that was prepared from plasma specimen in stratum with detectable VL, including those at lower than the lower limit of detection (LOD), which is 400 copies/ml in DBS using the CAP/CTM.

^bAll confidence intervals (CIs) are reported at the 95% confidence level.

^cIncludes any DPS that was prepared from plasma specimen in stratum with detectable VL, including those at lower than the LOD, which is 400 copies/ml in DPS using the CAP/CTM.

^dLOD of the CAP/CTM in plasma is 20 copies/ml.
