Detection of HAV RNA standards in serial 10-fold dilutions using real-time RT-PCR

Log dilution	No. of copies		CV (%)a
	Mean	SD
0b	900,333	25,423	2.8
1	82,500	5,703	6.9
2	8,110	690	8.5
3	1,237	122	9.9
4	110	6	5.5
5	6	2	40.0
6	0.2	0.4	173.2

^aThe CV of a set of data was determined by dividing the standard deviation by the arithmetic mean of the measured values.

^bHAV RNA standard was 9.8 × 10⁵ copies.
