Claims (8)

  1. 毛細管通路が、該通路を経由して所定の経路に沿って、毛細管作用により体液サンプルの移動を誘導するように設計され、サンプル中の検体の濃度に相関している第1測定値を得るための該通路と電気的に伝達される第1セット電極と、
    前記第1測定値に影響するサンプルの特性と相関する第2測定値を得るための該通路と電気的に伝達される第2セット電極を含み、
    前記第1セット電極および第2セット電極により、交絡変数の存在下でさえも、体液中の検体を正確に測定する毛細管通路を定めるテストストリップであって、
    前記第1および第2セット電極のうちの一方が実質的に平行な互いに噛み合ったフィンガーを有するマイクロ電極対を含み、各電極が少なくとも2つのフィンガーを有し、さらに各フィンガーが当該一方のセット電極中の他の最近接フィンガーから約50ミクロン未満の第1の距離であり、かつ
    前記第1および第2セット電極のうちの他方が少なくとも50ミクロンの第2の距離だけ離間した各々1つのフィンガーを有する一対のマクロ電極を含む
    ことを特徴とするテストストリップ。
  2. 該第1セット電極が、実質的に平行な互いに噛み合ったフィンガーである電極対を含む請求項1記載のテストストリップ。
  3. 該第2セット電極が、実質的に平行な互いに噛み合ったフィンガーである電極対を含む請求項1記載のテストストリップ。
  4. サンプルが、通路中の所定の距離を入ってくるときに定量する経路と電気的に伝達される第3セット電極をさらに含む請求項1、2または3記載のテストストリップ。
  5. 第3セット電極が、一対のサンプル充足電極からなり、両者は、第1セット電極および第2セット電極よりも通路の入り口から遠い請求項4記載のテストストリップ。
  6. 体液サンプル中の検体濃度を測定する方法であって、
    請求項1〜のいずれか1項によるテストストリップを提供する工程、
    第1セット電極に対する第1電気信号の印加に対する第1応答を取得する工程、
    第2セット電極に対する第2電気信号の印加に対する第2応答を取得する工程、
    サンプル中の検体濃度測定を導くために、第1応答および第2応答を使用する工程
    を含むことを特徴とする方法。
  7. 前記第1および第2応答を取得する工程の前に、テストストリップへのサンプルの適用を検出することを、さらに包含する請求項記載の方法。
  8. 前記第1および第2応答を取得する工程の前に、サンプルの体積の充足性を検出することを、さらに包含する請求項または記載の方法。
