Overview
Laboratory tests used in the diagnosis of chlamydia infection include nucleic acid amplification tests (NAAT) such as polymerase chain reaction (PCR), transcription mediated amplification (TMA), and the DNA strand displacement assay (SDA). NAAT for chlamydia infection may be performed on swab specimens sampled from the cervix (women) or urethra (men), on self-collected vaginal swabs, or on voided urine.[1][2][3]
Laboratory Findings
Laboratory findings consistent with the diagnosis of Chlamydial infection and its complications include:
Type of Chlamydia | Tests | Findings |
---|---|---|
Neonatal Conjuctivitis | CBC | Normal |
ESR | Normal | |
Neonatal pneumonia | CBC | Absolute increase in eosinophil count |
ESR | Increased | |
CRP | Increased | |
Genital infection | CBC | Increased leukocyte count |
Urinalysis | >5 WBCS per high power field | |
ESR | Normal or increased | |
CRP | Normal or increased | |
Atypical pneumonia | CBC | Increased absolute eosinophil count |
Fitz Hugh Curtis Syndrome | CBC | Increased leukocytes |
LFTS | Normal | |
ESR | Normal or increased | |
D Dimer | Normal or increased |
