Abstract

Objective: C reactive protein’s (CRP) measurement is frequently delayed due to transportation of blood and technical problems of laboratory devices. In this study we investigated the changes in CRP levels of sera stored in refr igerated conditions. Method: The CRP levels of sera were detected with Behring nephelometry system without any delay. The serum of 50 patients with CRP levels between 12.6 mg/L and 203 mg/L were kept uncovered at +4 o C. The CRP measurements we re repeated at two different times, after 3 and 7 days from the first measurement. Obtained CRP levels were evaluated statistically. Result: The CRP mean level from the first measurements was 55.83 mg/L, where three days later the mean level increased to 76.35 mg/L and seven days later, the mean level decreased to 60.99 mg/L. The difference between first and three days measurements was found st atistically significant however there was no significant difference between the first and seven days. Conclusion: If samples can not be analyzed for CRP immediately due to a technical glitch, the right approach would be to work in collaboration with clinicians and request a new sample if possible. Furthermore, this study is important as it shows a need for more comprehensive studies on time- dependent change of CRP le vels in the next days and under different conditions and causes for that change.

Özet

Amaç: C-reaktif protein (CRP)’in ölçümünde, al ı nan kanlar ı n laboratuvara ula ş t ı r ı lmas ı s ı ras ı nda veya laboratuvar cihazlar ı nda meydana gelen teknik aksakl ı klar nedeniyle gecikmeler ya ş anabilmektedir. Çal ı ş mada, bu gibi durumlarda buzdolab ı ş artlar ı nda bekletilen serumlardaki CRP düzeylerinde meydana gelebilecek de ğ i ş imlerin saptanmas ı amaçlanm ı ş t ı r. Yöntem: Behring Nefelometri sistemi ile bekletilmeden CRP ölçümleri yap ı lan ve düzeyleri 12.6 mg/L ile 203 mg/L aras ı nda de ğ i ş en 50 hastan ı n serumlar ı a ğ z ı aç ı k biçimde +4 o C’de bekletildi. Bekletilen bu serumlar ı n, ilk ölçümlerinden 3 gün ve 7 gün sonra olmak üzere iki ayr ı zamanda CRP ölçümleri tekrarland ı . Üç farkl ı zamanda elde edilen sonuçlar istatistiksel olarak de ğ erlendirildi. Bulgular: İ lk gün yap ı lan ölçümlerde ortalama CRP düzeyinin 55.83 mg/L oldu ğ u, üç gün sonra yap ı lan ölçümlerde ortalaman ı n 76.35 mg/L’ye yükseldi ğ i, yedi gün sonra yap ı lan ölçümlerde ise ortalaman ı n ilk günkü de ğ erlere yakla ş arak 60.99 mg/L’ye dü ş tü ğ ü gözlendi. İ lk gün ve üç gün sonra yap ı lan ölçümler aras ı ndaki fark istatistiksel olarak anlaml ı bulunurken, ilk gün ve yedi gün sonras ı ölçümler aras ı nda anlaml ı bir fark bulunamad ı . Sonuç: Teknik aksakl ı klar nedeni ile CRP’nin hemen çal ı ş ı lamayaca ğ ı durumlarda klinisyenlerle i ş birli ğ i içerisinde olunarak gerekirse yeni numune istenmesi do ğ ru bir yakla ş ı m olacakt ı r. Ayr ı ca bu çal ı ş ma, sonraki günlerde ve farkl ı ko ş ullarda CRP düzeylerinin zamana ba ğ l ı de ğ i ş iminin ve nedenlerinin belirlenmesi için daha kapsaml ı çal ı ş malar ı n gereklili ğ ini ortaya koymas ı aç ı s ı ndan önemlidir.
