Diagnostic Values of Complete Blood Count in Patients with Urinary Tract Infection

The study was carried out in Tikrit city from January 1^st to July 1^st 2018. These patients admitted to Sallah Al-Deen general hospital and primary health care centers in Tikrit city. The number of patients with urinary tract infection was 300 patients whom their ages ranged from 2 months to 70 years. The control group included 100 individuals who appeared healthy with no history of UTI. Urine direct and indirect examination was held for all the patients and control. 210 samples of cultured specimens gave positive results in culture media. Most isolates were Staph. aureus with 25%. Staph. saprophyticus 24%, E. coli 16%, K. pneumoneae 5%. Pseudomonas aeruginosa, Proteus and Citrobacter frundii were present in about 2%, 5% and 7% respectively. Yeast-like fungi, Candida albicans and Candida spp. was also found 7% and 2% respectively. All samples have been subjected to complete blood count with emphasis on platelets; platelet count, distribution width (PDW) and mean platelet volume (MPV). Platelet count showed a significantly higher values in patients with UTI in comparison to control group. Platelet count and parameters showed a significant increase in gram positive bacteria specifically higher for Staph. saprophyticus. which means there is maybe a correlation between platelets and the type of the causative agent of infection.
