2.
自2018年10月12日起,因儀器試劑合約異動,異動血中藥物濃度監測項目及藥物濫用檢驗項目
 2018.10.09

檢驗醫學部通知

   檢字10737

  期:20181009

受文者:彰基體系全體同工

  旨:

1.    轉換血中藥物濃度監測項目及藥物濫用檢驗項目的檢驗儀器及試劑,因此異動血中藥物濃度監測範圍。

2.    修改Phenytoin(FDPENYFRDENY)採檢容器

3.    停止Serum Tricyclic antidepressants (TCA) screening檢驗(檢驗醫令FRDTCAFDPTCA)

4.    新增Tacrolimus急作醫令FRDTAC

  明:

1.20181012日起,因儀器試劑合約異動,因此血中藥物濃度監測項目及藥物濫用檢驗項目的檢驗儀器由原Siemens Dimension RXL轉換為Beckman Coulter DXC800Abbott Architect,同時異動相關檢驗試劑。檢驗儀器異動如下表:

檢驗項目

檢測儀器

AcetaminophenGentamicinPhenytoinPhenobarbitalCarbamazepineVancomycinDigoxinValproic AcidAlcoholLithiumTheophyline

Beckman Coulter DXC800

Benzodiazepine (Urine)AmphetaminesOpiateAlcohol

Beckman Coulter DXC800

TacrolimusSirolimusCyclosporine

Abbott Architect i system

2.血中藥物濃度監測項目檢驗儀器及試劑異動,因此重新審查治療區間照會藥品血中濃度監控小組,異動如下表:

檢驗項目

異動內容說明

Acetaminophen

取消Toxic interval說明

Gentamicin

1.   取消Peak therapeutic range說明

2.   新增報告備註說明:

Trough level:

Adult:

Serious infections: 0.5~1.0 µg/mL.

Life-threatening infections: 1.0~2.0 µg/mL.

Synergy against gram-positive organisms: <1.0 µg/mL.

Pediatric:

Traditional dosing: <2.0 µg/mL.

Once daily dosing: < 0.5~1.0 µg/mL.

Phenobarbital

取消Toxic interval說明

Vancomycin

1.   異動Peak therapeutic range: 20.0~40.0 μg/mL

2.   新增報告備註說明:For complicated infections (eg, bacteremia, endocarditis, osteomyelitis, meningitis, and hospital-acquired pneumonia caused by S. aureus) or infections associated with severe sepsis or septic shock, trough concentrations of 15 to 20 µg/mL are recommended to improve penetration and improve clinical outcomes

Digoxin

1.   異動Therapeutic range: 0.50~2.00 ng/mL

2.   新增報告備註說明

Heart failure: 0.5 to 0.9 ng/mL

Adults: 0.8 to 2.0 ng/mL; <0.5 ng/mL probably indicates underdigitalization unless there are special circumstances.

A serum concentration ≥1.2 ng/mL may be associated with increased all-cause mortality in patients with atrial fibrillation (regardless of heart failure)

Valproic Acid

Mania: Clinical response seen with trough levels between 50.0~125.0 µg/mL

Lithium

1.   取消Toxic interval說明

2.   新增報告備註說明:

治療最低濃度:1.0~1.2 mmol/L(服藥後12小時)

最低有效濃度:0.6 mmol/L

Theophyline

1.   異動Therapeutic range 5.0~20.0

2.   新增報告備註說明:

Children: 5.0~15.0 µg/mL;

Adults: 10.0~20.0 µg/mL

Sirolimus

1.   異動Therapeutic range: 4.0~15.0 ng/mL

新增報告備註說明:Optimal ranges depend on patients’ clinical state

Cyclosproine

1.   異動Therapeutic range: 100~400 ng/mL

2.   新增報告備註說明:(1)Renal transplant:

(A)無公認之可用治療區間;

(B)0~90天之濃度為250~350 ng/mL,>90天之濃度為125~250 ng/mL,>1年之濃度為75~125 ng/mL

(2)General range of 100~400 ng/mL; refer to institutional protocol for specific therapeutic ranges.

(3)Toxic level: Not well defined, nephrotoxicity may occur at any level.

Tacrolimus

1.   新增Therapeutic range: 4.0~20.0 ng/mL

2.   新增報告備註說明:Vary with organ transplantation, patient risk factors, concomitant immunosuppression, and time post-transplant)

1. liver transplant: early post-trasnplant 7~10; over one year 4~6

2. kidney transplant: < 6 months 5~15 ng/mL; > 6 months: 5~10 ng/mL

3. Prevention of graft-versus-host disease: 10~20 ng/mL

 

3.修改Phenytoin(FDPENYFRDENY)採檢容器為3號綠頭管(Lithium heparin tube);得以02號黃頭管(Serum separator tube )代替。

4.因新檢驗儀器試劑合約儀器無Serum Tricyclic antidepressants (TCA)檢驗試劑,因此即日起暫停此檢驗項目(檢驗醫令FRDTCAFDPTCA)服務,若臨床欲評估Tricyclic antidepressants (TCA)使用情形,可檢測Urine Tricyclic antidepressants (TCA) screening檢驗,可開立Urine Drug Abuse Screening tests panel(檢驗代碼FRDDAT1FRDDAT2FRDDAT3)

5.新增Tacrolimus急作醫令FRDTAC,檢驗時效2小時。

6.檢驗項目採檢相關注意事項,包含病人準備、採檢及傳送方式、報告完成時間及生物參考區間等,請參考本院主網頁檢驗資訊查詢系統(http://www2.cch.org.tw/labsearch/)及各項目網頁採檢手冊說明。

7. 相關問題,請聯絡檢驗醫學部主任醫檢師蕭玉鑫,分機5940
