Precision

Intra-assay Precision (Precision within an assay):Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Intra-Assay CV: ≤4.7%

Inter-assay Precision (Precision between assays):Three samples of known concentration were tested in five separate assays to assess inter-assay precision.

Inter-Assay CV: ≤7.5%

Recovery

Recovery was determined by spiking various levels of Procalcitonin into serum and plasma.

Sample Type	Average(%)	Recovery Range(%)
Serum	99	93-105
Plasma	101	95-107

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Procalcitonin and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Sample	1：2	1:4	1:8	1:16
serum(n=5)	112-122%	90-100%	93-103%	105-117%
EDTA plasma(n=5)	103-112%	106-116%	81-92%	99-108%
heparin plasma(n=5)	83-96%	105-114%	88-98%	98-109%

General Annotation

Sub Unit:

N/A

Function:

The level of procalcitonin in the blood stream of healthy individuals is below the limit of detection (10 pg/mL) of clinical assays. The level of procalcitonin raises in a response to a proinflammatory stimulus, especially of bacterial origin. In this case, it is produced mainly by the cells of the lung and the intestine. It does not raise significantly with viral or non-infectious inflammations. With the derangements that a severe infection with an associated systemic response brings, the blood levels of procalcitonin may rise to 100 ng/ml. In serum, procalcitonin has a half-life of 25 to 30 hours. Remarkably the high procalcitonin levels produced during infections are not followed by a parallel increase in calcitonin or serum calcium levels.

Location:

Procalcitonin (PCT) is a peptide precursor of the hormone calcitonin, the latter being involved with calcium homeostasis. It is composed of 116 amino acids and is produced by parafollicular cells (C cells) of the thyroid and by the neuroendocrine cells of the lung and the intestine.
