Wright's stain is a hematologic stain that facilitates the differentiation of blood cell types. Wright's stain is classically a mixture of eosin (red) and methylene blue dyes. It is used primarily to stain peripheral blood smears, urine samples, and bone marrow aspirates. Wright's stain provides a manual or automated stain for bone marrow and peripheral blood smears[1].

Eosinophiluria
Clin Lab Med 1988 Sep;8(3):555-65.PMID:2458885doi
Hansel's stain is a simple technique that can easily be performed in a clinical or office setting. It allows for improved detection of the eosinophiluria when compared with conventional Wright's stain. The mechanism underlying the superiority of the Hansel's stain remains to be elucidated. Eosinophiluria demonstrated by Hansel's stain appears to be a sensitive marker for drug-induced acute interstitial nephritis and probably allows differentiation from acute tubular necrosis. However, the spectrum of eosinophiluria also includes acute glomerulonephritis, rapidly progressive glomerulonephritis, prostatitis, and urinary tract obstruction. Therefore, the finding of eosinophiluria on Hansel's stain clearly cannot be considered diagnostic of acute interstitial nephritis. In the absence of renal biopsy or other clinical clues to suggest the diagnosis, eosinophiluria should not be used as the sole criterion for the diagnosis of acute interstitial nephritis or a a justification for empiric steroid therapy.
Usefulness of the stool Wright's stain in the emergency department
J Emerg Med 1988 Nov-Dec;6(6):483-6.PMID:2464634DOI:10.1016/0736-4679(88)90404-0.
A prospective study was conducted to determine if a Wright's stain of stool specimen to detect fecal leukocytes was accurate in predicting the presence of a bacterial pathogen on stool culture. Entry criteria were patient age greater than or equal to 3 months and diarrhea of greater than 1 day. The patient population was drawn from an urban county hospital emergency department on the Texas-Mexican border. A total of 69 patients were evaluated by both routine stool culture and stool Wright's stain. Twenty-three were evaluated for parasitic pathogens. There were seventeen cultures positive for bacterial pathogens and twenty-three positive Wright's stains. Bacterial isolates included Shigella, Salmonella and Campylobacter. Also detected were Giardia, Shistosoma, Blastocytis and Cryptosporidium. The sensitivity of a Wright's stain positive for fecal leukocytes for the presence of a bacterial pathogen by culture was 82%, with a specificity of 83%. These were significantly correlated with a positive culture for a bacterial pathogen (P less than .01). The predictive value of a positive result was 61%, and predictive value of a negative result was 94%, for bacterial pathogens. The Wright's stain is a useful tool for the early presumptive diagnosis of infectious bacterial diarrhea in the emergency department.
Wright's stain in rapid diagnosis of Pneumocystis carinii
Am J Clin Pathol 1984 Apr;81(4):511-4.PMID:6199969DOI:10.1093/ajcp/81.4.511.
The conventional Hematology Wright's stain has been used in touch preparation from open lung biopsies to identify Pneumocystis carinii. A 100% positive correlation has been found using this rapid and readily available technique when compared to the conventional silver stain and permanent histologic sections.
Improved stability of methanolic Wright's stain with additive reagents
Stain Technol 1981 Jul;56(4):251-63.PMID:6171055DOI:10.3109/10520298109067320.
Additive reagents have been investigated to improve the stability of methanolic Wright's stain. The addition of ammonium halides, monoalkylamine hydrochlorides, dialkylamine hydrochlorides or trialkylamine hydrochlorides to methanolic Wright's stain was found to enhance the stability of stain components in methanol. No change in performance is observed with these additives present. Random precipitation in the stain solution was still observed with the addition of ammonium halides and monoalkylamine hydrochlorides. No precipitation was found in stain solutions containing hydrochlorides of most dialkylamines and trialkylamines. Of the compounds evaluated, 0.6% diethylamine hydrochloride added to methanolic stain solutions produced the most desirable overall results. Mechanisms of stabilization and precipitation in these stain solutions are proposed. Essentially, separation of the thiazine-eosinate ion pair through interaction with an appropriate additive increases stain stability. The solubilities of thiazine-eosinate or additive cation-eosinate ion pairs in methanol determine the formation of precipitate in such stain solutions.
Field's stain--a rapid staining method for Acanthamoeba spp
Parasitol Res 1999 Oct;85(10):791-3.PMID:10494803DOI:10.1007/s004360050634.
Acanthamoeba sp. is a free-living amoeba known to cause chronic central nervous system infection or eye infection in humans. Many cases remain undetected for want of a good detection system. We report for the first time a rapid staining method to facilitate the identification of Acanthamoeba sp. using the modified Field's staining technique. A. castellanii, which was used in the present experiment, is maintained in our laboratory in mycological peptone medium (Gibco). The cultures were pooled together and smears were made on glass slides for staining purposes. Different types of stains such as Field's stain, modified Field's stain, Wright's stain, Giemsa stain, Ziehl-Neelsen stain, and trichrome stain were used to determine the best stain for the identification of this amoeba. The concentration of various stains and the duration of staining were varied to provide the best color and contrast for each stain. Acanthamoeba was also obtained from the brain of experimentally infected mice and was stained with various stains as mentioned above to determine the best stain for use in identifying the presence of this parasite in experimentally infected animals. The modified Field's stain gives a very good color contrast as compared with other stains. Furthermore, it takes only 20 s to be carried out using the least number of reagents, making it suitable for both laboratory and field use.
